This product has excellent food contact safety, meeting the stringent food packaging material standards in the world. Its high barrier performance can effectively lock the freshness and flavor of food, extending the shelf life of products by 3-5 times compared with ordinary plastic packaging films. It supports microwave heating without releasing harmful substances, meeting the daily packaging needs of consumers for convenient food. The film has good printing adaptability, which can clearly print product information, brand logos and nutritional labels, improving the commercial value of packaged products. It also has good toughness and puncture resistance, avoiding damage during packaging and transportation, and the optimized heat-sealing process ensures firm sealing without leakage. In addition, it can be matched with different packaging equipment such as vacuum packaging machines and modified atmosphere packaging machines, adapting to various production scenarios.
The product has a thickness specification of 70-90μm, which can be customized according to the specific packaging needs. The aluminum foil layer is 6-8μm thick, providing excellent barrier performance for oxygen, water vapor and odor. The outer PET layer is 12-15μm thick, providing good scratch resistance and printing adaptability, while the inner cast polyethylene layer is 45-65μm thick, ensuring reliable heat-sealing performance and direct contact with food. The tensile strength in the longitudinal direction is ≥80MPa, and the transverse direction is ≥60MPa; the heat seal strength is ≥2.8N/15mm. The oxygen barrier rate is ≤1.0 cm³/(m²·24h·atm), and the water vapor barrier rate is ≤0.5 g/(m²·24h). It supports gravure printing and flexographic printing, and the surface can be treated with corona to improve printing fastness. The product is supplied in rolls with a width of 200-1200mm and a standard roll length of 2000m, and can also be cut into corresponding specifications according to customer requirements. It has passed FDA 21 CFR and EU 10/2011 food safety certifications, ensuring that it can be safely used for food packaging.
This product is mainly suitable for the vacuum and modified atmosphere packaging of various foods, including cooked meat products, roasted seeds and nuts, dried fruits, snack foods, cheese and other perishable or odor-sensitive products. It can be used in food processing factories, large-scale food distribution centers, supermarket fresh food packaging and other scenarios. In the catering industry, it can be used for the packaging of takeaway food and leftovers, meeting the needs of consumers for convenient and fresh food. At the same time, it can be matched with different packaging equipment, supporting automated packaging production, improving production efficiency and reducing packaging costs. It can also be used for the packaging of non-food products with strict odor isolation requirements, such as cosmetics samples and electronic components, expanding its application scope.
