In the early days, coffee was often packaged in simple sacks or bags made from natural materials, such as burlap or hemp. These materials were not very airtight, so they could not keep coffee fresh for long periods of time. Vacuum sealed packaging was invented during the 1900s. This packaging removes all of the air from the packaging, which helps to keep coffee fresh for an extended period of time. Vacuum sealed packaging is also lightweight and relatively inexpensive, so it quickly became the most popular type of coffee packaging.

In recent years, there has been a growing trend towards more sustainable coffee packaging. This trend is driven by concerns about the environmental impact of traditional coffee packaging materials, such as plastic and tin.

Overview of Coffee Packaging

Coffee packaging refers to the process of packaging and presenting coffee beans or ground coffee for distribution, sale, and consumption. Coffee packaging serves several important purposes, including preserving the freshness and flavor of the coffee, protecting it from external elements such as light, moisture, and oxygen, and providing information to consumers.

Coffee packaging plays a crucial role in ensuring that coffee reaches consumers in optimal condition, with its flavor and aroma preserved. It also serves as a means of communication between coffee producers and consumers, conveying information about the coffee's characteristics and the values of the company that produces it.

Integrity testing of coffee packaging ensures that the packaging is free of leaks and defects that could compromise the quality of the coffee. This is important to do, as leaks can allow oxygen, moisture, and light to enter the packaging, which can all degrade the flavor of the coffee.

Here are some of the benefits of integrity testing for coffee packaging:

• It can help prevent coffee from going stale or developing off-flavors.
• It can help protect coffee from contamination.
• It can help ensure that coffee meets quality standards.
• It can help reduce product recalls.
• It can help improve customer satisfaction.

Quality Testing Using Vacuum Decay Technology

Vacuum decay technology is a non-destructive method for testing the integrity of coffee packaging. It is a Container Closure Integrity Test (CCIT) method with a proven capability of non-destructively testing packaging at the production line with unmatched reliability and sensitivity. Non-destructive testing not only allows a greater understanding of package quality, but also reduces waste as compared to destructive test methods. Waste reduction, in turn, results in a higher return on investment and brings operations closer to green initiatives.

Vacuum decay technology operates by placing sample packages in a closely fitting evacuation test chamber, which is equipped with an external vacuum source. Single or dual vacuum transducer technology is used to monitor the test chamber for both the level of vacuum as well as the change in vacuum over a predetermined test time. The changes in absolute and differential vacuum indicate the presence of leaks and defects within the package. VeriPac series is a practical alternative to destructive test methods and can precisely detect leaks as small as 5 microns, identifying process issues before they become critical, avoiding catastrophic quality deviations.

Benefits of Vacuum Decay Test System

• Non-destructive technology.
• ASTM Test Method F2338, FDA Consensus Standard and referenced in USP 1207 Guidelines.
• Accurate, repeatable results.
• Pass/fail results backed by quantitative test data.
• Completely tool-less with no changeover to test different packaging formats.
• Identifies which cavity is defective.
• Eliminates destructive, subjective testing methods.

Vacuum decay technology is a valuable tool for ensuring the quality of coffee packaging. It can help prevent coffee from going stale or developing off-flavors. It can also help protect coffee from contamination. If you are a coffee roaster or retailer, integrity testing of coffee packaging is an important quality control measure that you should implement.

Automated Container Closure Integrity Testing (CCIT) is a specialized form of testing that focuses on verifying the integrity of the container closure systems of several types of containers used to store and transport products. This can include vials, pre-filled syringes, bottles, pouches, and other types of containers. The container closure system includes the closure device (such as a stopper or cap) and the container or package itself (such as a glass or plastic vial or bottle), and it is essential to ensure that it is properly sealed so that it does not allow any leaks or contaminants to enter the container.

Automated CCI testing of pre-filled syringes involve using specialized testing equipment and techniques to simulate real-world conditions and test the container closure system's integrity. This testing process can be done in the laboratory by an operator or fully automated to increase efficiency and accuracy.

Testing Pre-filled Syringes Using E-Scan RTX

The E-Scan RTX platform is a modular, fully automated container closure integrity solution for pre-filled syringes. The RTX is a practical and dependable CCI solution with a dynamic robotic design that is adjusted to meet your production needs. This robust, flexible platform uses MicroCurrent HVLD technology, a revolutionary form of HVLD that is the optimal CCI solution for fragile, high-risk biologic liquids. It is appropriate for batch release testing at the production line, in the lab, and provides a quick PASS/FAIL result with a test cycle of only seconds.

A robotic arm will track and pick up nested syringe trays from a standard single lane conveyor. The robot removes the syringes from the nested tray and rotates the syringes through two test stations, one to detect needle shield defects and the other to inspect the rest of the syringe body. The test starts automatically and gives a fixed PASS/FAIL signal on completion of the test. An adjustable failure reference can be set to allow PASS/FAIL based on a predetermined LOD (limit of detection) setting in the initial recipe. After testing, syringes are automatically loaded back into the syringe tray, defective syringes are collected in the reject tray.

Benefits of E-Scan RTX

• MicroCurrent HVLD technology is effective across all parenteral products, including biologics and extremely low conductivity liquids including sterile water (WFI).
• Listed in USP Chapter 1207 as a recommended method for parenteral liquid package inspection.
• Robust method and good Signal-Noise-Ratio between good and defective products.
• Low voltage exposure reduces the production of ozone.

Automated pre-filled syringe testing is critical to ensuring the safety and efficacy of pre-filled syringes used in the pharmaceutical industry. By using automated testing techniques, manufacturers can ensure that the container closure system is reliable and free from defects, reducing the risk of contamination or other safety concerns.

Tyvek is a highly durable and lightweight material that is commonly used in the medical industry for the packaging and sterilization of medical devices and equipment. It is a non-woven material made from high-density polyethylene fibers that are bonded together using heat and pressure. Medical device manufacturers and packaging professionals prefer Tyvek packaging because it is a sterile barrier that protects against bacteria and other contaminants. Tyvek is also breathable, allowing for sterilization methods such as ethylene oxide and gamma irradiation to be used effectively.

Tyvek packaging is used in a variety of medical applications, including surgical gowns, drapes, and covers, as well as in medical device packaging such as catheters, implants, and instruments. Its use in the medical industry is regulated by government agencies such as the FDA to ensure that it meets the necessary standards for safety, sterility and efficacy.

What are the Challenges Associated with Tyvek Package Testing?

Leak testing of Tyvek packages is a critical step in ensuring the integrity of the package and the safety of its contents. However, there are several challenges associated with leak testing Tyvek packages, including:

• Sensitivity of the test method: The sensitivity of the leak testing method can impact the ability to detect leaks in Tyvek packages. For example, some testing methods may not be able to detect very small leaks or may be impacted by the size or shape of the package.
• Environmental conditions: Environmental factors, such as temperature, humidity, and pressure, can impact the results of the leak test. For example, changes in temperature can cause the package to expand or contract, which can impact the tightness of the seal and the results of the test.
• Interference with product properties: Some leak testing methods may use test gases or liquids that can interact with the product inside the package. For example, the test gas may cause the product to degrade or impact its efficacy, which can affect the overall performance of the package.

In summary, leak testing of Tyvek packages requires careful consideration of the test method, the packaging process, and the environmental conditions to ensure accurate and reliable results.

Testing Tyvek Packages Using Airborne Ultrasound Technology

With today’s sensory technology advancements, Tyvek packages can be tested using Airborne Ultrasound technology. Airborne Ultrasound technology is a seal quality testing method that uses airborne ultrasound to evaluate seals for flaws and defects non-destructively. It is an ASTM Test Method F3004 for testing the seal quality and a recognized FDA standard for seal quality inspection. These tests are mostly carried out to improve seal quality inspection of pouches, flexible packaging, and tray seals. Tyvek, paper, foil, film, aluminum, plastic, and poly are just a few of the packaging materials that may be used with Airborne Ultrasound technology to enable thorough seal quality evaluations.

In this method, sound waves are reflected as ultrasonic waves are transmitted through the packaging seal. If there is a leak or flaw, the signal intensity is decreased or lost. To find the leak, these differences are closely monitored. Most leak test techniques encounter the problem of being unable to identify non-leaking defects. By using Airborne Ultrasound technology, users may recognize a variety of seal faults, including visible and invisible, leaking and non-leaking, process-related and random. Airborne ultrasound can be applied in the laboratory for offline in-depth seal quality analysis as well as for 100% online seal quality inspection on the production line.

Benefits of Airborne Ultrasound Technology

• Non-destructive, non-subjective, no sample preparation.
• Deterministic inspection method producing quantitative results.
• Can be integrated for 100% online defect detection of the final pouch seal.
• Repeatable and reliable results.
• Eliminates subjective manual vision inspection methods.
• Characterizes overall quality and uniformity of the seal.
• Economical cost-effective solution for seal integrity testing the final pouch seal.

The method used for leak testing Tyvek packages will depend on the specific requirements of the medical device or equipment being packaged and the regulations set forth by regulatory agencies such as the FDA. It is important to use a validated and appropriate method for leak testing to ensure the safety and effectiveness of the packaged medical devices or equipment. Airborne Ultrasound is one such technique.

Container Closure Integrity (CCI) refers to whether a container keeps the sterile barrier intact. Environmental pollutants can quickly turn a life-saving therapy into a microbial soup if there is a leak or breach of the sterile barrier. The CCIT of blister packages is a critical process in ensuring the quality and safety of pharmaceutical products. Blister packages are commonly used to package solid-dose medications such as tablet and capsules.

The CCI testing of blister packages is performed to ensure that the package is properly sealed and that there are no leaks or defects that could compromise the quality of the medication inside. This testing is important because if the package is not properly sealed, moisture and oxygen can enter, potentially degrading the medication and reducing its effectiveness.

Overview of OptiPac Technology

OptiPac One-Touch Tool-less Leak Detection Technology is a non-destructive method for testing the integrity of blister packaging that is designed to detect any leaks or defects in the package's seal. OptiPac uses volumetric imaging technology to measure the blister cavities under vacuum and identify leaks. The OptiPac applies controlled inputs and measurable outputs without the inconvenience and reliability concerns of the dye ingress approach. It is designed with One-Touch Technology to accomplish a quick test cycle needing no changeover or tools for various blister formats. Unlike other non-destructive blister package inspection systems that demand complicated parameter modifications, OptiPac requires no tooling replacement with new blister package forms.

The test begins by placing the sample on the testing area for vacuum-based measurement. Vacuum is pulled to a definite vacuum after pushing the start button. Under vacuum, blisters expand and push air out of the blister through any leaks that may be present. If there is a leak in the blister, air leaks into the chamber and collapses the blister package. The defective blister cavities are identified using a volumetric measurement reading during the dynamic vacuum test cycle. Along with the quantitative measurement related to each package test, a clear pass/fail result is displayed.

In addition to selecting the appropriate method for leak testing, other factors to consider when performing blister package leak testing include the type of material used for the package, the seal strength of the package, the packaging process, and the potential for environmental factors to affect the package's integrity. By carefully considering these factors and implementing an effective leak testing (pharmaceutical package testing) process, pharmaceutical companies can ensure that their products are of the highest quality and meet regulatory requirements.

We all know that the primary function of any package is storing, handling & protecting the product. So, what is package integrity? Package integrity is defined as a package’s ability to protect its contents from potential hazards that include various physical, microbial & chemical factors. Its usefulness may have many nuances depending on the products & content. But industries like pharmaceutical, nutrition & medical device, deal with lifesaving & sustaining products that are shipped across the globe. Any discontinuity in the package can result in the contamination of the product making a life-saving product into a life-threatening one. Therefore, package integrity is imperative to ensure the safety of the products at the time of use.

The selection of the appropriate package inspection method is essential to maintain the quality standards that the regulatory bodies stand by today. Since 2016, the United States Pharmacopeia (USP) released guidance encouraging the use of deterministic, reliable test methods. Package leak test methods offered by CCIT s.a. are all deterministic, non-destructive, quantitative test methods with a specific on the reliability of the test result to assure integrity at the highest level.

In today's world, with the popularity of health products continuing to rise, manufacturers must ensure products are packed properly. Because of this reason, the universal health-wise regulation has set a fixed standard for nutritional products packaging process. This is for the elimination of defects happening due to innate chemical reactions within the nutritional products. Such defects can expose products to oxygen, moisture or bacteria- compromising its quality and reducing shelf life.

Nutritional products including dairy products and protein powders are mostly shelf stable in nature. The high fat content in dairy products including cream, butter and ghee is prone to deterioration in its storage process, causing auto-oxidative reactions. The defects in the dairy products can be eliminated through proper nutritional packaging inspection only. Similarly, protein-based powders including soy and casein are extensively used as energy sources. Inefficiencies in packaging of such products can have an adverse effect on consumer’s health. Therefore, conducting package integrity testing of nutritional products are vital to eliminate defects in packaging as well as possibility of product contamination.

Vacuum Decay Technology – The Ideal Nutritional Packaging Inspection Solution

Vacuum Decay technology is a deterministic Container Closure Integrity test method for evaluating quality of nutritional product packaging. The non-destructive testing method improves quality of packaging and reduces wastage compared to destructive test methods.

Medical device quality control inspection is considered to be highly significant in ensuring safe delivery of medical devices from their place of origin to the market. However, tremendous development in medical technologies have challenged the medical device packaging industry to ensure quality and reliability in packaging

Adding to that, drug contamination is a serious concern in any medical industry- specifically for Class III medical devices. Class III medical devices are understood as devices that sustain or support life and are implanted, or present potential unreasonable risk of illness or injury. Since these devices are directly placed into human bodies, proper packaging is required to ensure quality of the product until it reaches the patient. Any breach in the packaging can cause contaminants to enter the device, causing major health risks. Hence, appropriate package integrity testing and seal quality inspection of Class III medical devices are required so as to ensure seal quality and sterile barrier integrity are maintained.

Initially, manufacturers heavily relied on visual inspection or other probabilistic test methods to inspect seal quality and integrity. However, such methods lacked accuracy and reliability in terms of test results. Hence, manufacturers are now shifting towards non-destructive method for evaluating seal quality and inspecting physical properties of a seal. One such technique that is increasingly becoming popular among medical device manufacturers is Airborne Ultrasound technology. It is an ASTM test method F3004 and FDA recognized standard for seal quality integrity testing. These tests are primarily conducted to provide advanced seal quality inspection of pouches, flexible packages and tray seals. The test is conducted by transmitting high frequency sound waves through the pouch seal area, providing a simple pass or fail result of seal quality. A linear scan analysis of the seal area will detect channel defects, misaligned seals, incomplete and missing seals immediately after the package has been sealed. If the system detects a package defect, the product can immediately be removed from the packaging and reworked. Process related defects can also be addressed and corrected immediately, which significantly reduces the quantity of defective packages produced

Airborne Ultrasound technology variants, namely Seal-Scan® and Seal-Sensor provide both, offline and online inspection of packages and accommodate various package specifications, test sensitivity and package handling requirements. Seal-Scan® offline systems offer in-depth seal quality analysis and seal characterization. Seal-Sensor online inspection systems for automated 100% inline scanning of pouch seals can be integrated into pouch production or pouch handling line. They provide a quick analysis of the seal area without tampering with the packaging to identify defects, such as incomplete or missing seals, wrinkles, channel defects and so on.
