The competition in the snack food market is extremely fierce , and the brand awareness of consumers is the key driver of sales. The opportunism in quality will affect the short-term profits and long-term operation of the company. If a consumer to buy a product, and this product has been bad, taste, mildew or have been oxidized, which may affect the decision of whether consumers will buy.    Packaging is important to look at the display shelves, because it gives consumers the most intuitive feelings, and many factors affect consumer perception of the product. Common snack food packaging formats include flexible packaging ( pouch , wrap and pouch ) , composite cans and modified atmosphere packaging (MAP) . These packages are ideal for packaging of snack foods such as nuts, snacks, potato chips, biscuits, biscuits, beef jerky, nutritional products, and breakfast nutritious foods, as well as providing consumers with stability (shelf life) and convenience (packaging Easy to open). Although each package reflects its unique advantages and the attractiveness of the product to consumers , each form of packaging faces different challenges and challenges in ensuring the integrity of the packaging and seals. Canned    Filling and sealing test requirements are high. A suitable oxygen-sensitive snack container—a canned, cost-effective solution—has a unique packaging test requirement and has a moisture-sensitive critical leak point. If the "bath method" is used for leak testing, the "trapped" air in the composite container will even "bubble" from the leaking container , which makes the subjective test more dependent on the quality inspector. Peel strength caps limit the degree of vacuum because vacuum can absorb the package and affect the detection accuracy of the "bath test method." Cardboard will also expand contact with moisture , which may also block severe sealing defects. At this time, the "water inspection method" cannot detect a certain range of leaks.    The vacuum decay method can be used in a variety of applications, such as shielding air that is “trapped†, and the test chamber is designed to ensure peel strength. The lid can perform non-destructive testing under high vacuum conditions, making the test result more accurate. The vacuum decay sealer can detect oxygen and moisture-sensitive leaks , while providing a more reliable, accurate, and suitable for a form of packaging designed for products that are sensitive to moisture and oxygen. solution. Modified Atmosphere Packaging ( MAP )    The integrity of the package is usually measured by measuring the amount of residual oxygen in the headspace of the package. This method requires that the product provided is stable in performance , and that measurement of headspace residual oxygen should be performed at different time periods. For production purposes, a six-day test is common and the measured oxygen content exceeds the maximum ( usually 3%) . A 50 μ m is sufficient leak shortened product shelf life, but the leak is typically able to pass a 6-day test O2. It may be that the O2 test will find quality problems , but the tested product has been placed on the pallet and stored in the warehouse (it will no longer be referred to the package sealing quality). Vacuum decay method can detect small leaks of 10 μ m, and can be found in time critical oxygen source of leaks, to prevent a wide range of quality problems.  Flexible packaging (pouches, wraps and pouches) Three-dimensional preformed packaging is the most common form of flexible packaging . At the same time , it also introduces systematic non-conforming products, which increase the risk. The three-dimensional preformed packaging process increases the complexity of producing high-quality packaging. The node and seal joints of the package are common channel leakage points. Cracking of aluminum foil film is common in creases of any material packaging film. The "water inspection method" is a traditional method for ensuring the integrity of flexible packaging and performing leak testing. This method depends on the air content in the package , and making the leak test relatively accurate depends on the headspace inside the package. Destructive forces also limit the vacuum level . Vacuum can be used in the packaging industry, but it also affects the sensitivity of the test method. PTI 's LEX-Chamber technology uses a patented soft film test chamber . The soft film limits the expansion of the package , allowing the highest test accuracy to be achieved while testing multiple package formats without changing the mold. Case Study: Peanuts "Peanut" is a very common food in the market and is often regarded as a worthless product , but when 90% of the cost is raw material, then the value of peanuts is another matter. Destructive seal testing costs a lot for cost. The cost of waste a year a production line casually more than $ 100,000. Cost-related destructive testing If you increase the packaging for testing, the cost increases and the ongoing operating costs of the quality team increase. At this time, the non-destructive sealing test will become a major contributor to the company. The non-destructive sealing test can provide more information to the quality inspection department, reduce the cost of waste production, and ultimately achieve better quality control.     As mentioned above, the application of sealing test for so many snack foods brings efficiency and cost benefits to the company. The veil of this mysterious instrument is revealed below. Snack Food Packaging Sealing Test Solution - VeriPacD Series The VeriPac Vacuum Attenuation Series Seal Tester has been proven to perform non-destructive sealing tests on the production line to reduce scrap and improve test performance. The system can reliably detect about 10 μ m leak, identifying the presence of process problems reach the critical point when the point of leakage. The outstanding feature of the VeriPacD series is the use of the patented FLEX-Chamber test chamber . The FLEX-Chamber test chamber does not require mold change when testing different sizes of pouches and is not affected by packaging changes. It can also test multiple packages in the same test cycle. The VeriPac series provides qualitative results ( pass / fail ) as well as quantitative data that correlates with leak rate and leak size. VeriPac series for destructive sealing test is a practical choice because it eliminates the subjective test results. The "water inspection method" also increases the risk of bacteria and moisture intrusion when the product is packaged. Case studies show that providing vacuum decay method compared to destructive testing, vacuum decay method with a very fast return on investment, good packaging has not been discarded, greatly reduce the quality of the testing process waste. This creates effective product inventory at the factory and retail levels.
