Food Industry

In the snack industry, composite plastic packaging bags, thanks to their multi-layered material combination, have become a popular choice for storing, preserving, and displaying a variety of snacks. Specific applications include:

1.Extending the shelf life of snacks: PET/AL/PE composite bags are often used for snacks susceptible to oxidation and moisture, such as nuts and dried meats. They block air and light, slowing spoilage. For example, bagged walnuts and beef jerky are often packaged this way.

2.Adapting to different snack packaging formats: PET/NY/PE composite bags are often used for snacks that need to protect against moisture and maintain a crisp texture, such as potato chips and puffed foods. Their toughness and puncture resistance prevent damage during transportation.

3.Improving consumer convenience: Some snack packaging, such as individually wrapped biscuits, uses easy-tear composite bags for easy opening. Other composite bags, such as dried fruit bags, feature self-sealing strips that can be resealed after opening, reducing waste caused by moisture.

4、Enhancing product display and marketing: Transparent composite bags, such as PET/PE composite bags, clearly display snacks (such as colorful candies and baked goods), attracting consumers. The surface of the composite bag can also be printed with brand information and flavor descriptions to enhance product recognition.

By combining multiple materials and functional designs, composite plastic packaging bags not only address the issues of freshness preservation and protection during snack storage, but also address consumer convenience and marketing needs, providing strong support for product distribution and sales in the snack industry.
