What is the trend of plastic packaging in the food industry?

Modern food packaging not only provides physical protection for food and content, but also helps extend the shelf life of food, provide product information and display brand image, and is more convenient for consumers to use daily. Compared to other packaging materials and forms, such as glass, metal and hard plastic packaging, soft plastic packaging is more environmentally friendly, saving raw materials and transportation costs, so as to better meet the needs of the modern packaging industry.

The flexible packaging technology uses a unique lightweight design. Durable handles designed in accordance with ergonomic principles can help users accurately dump. When vacant, the packaging bags can be flattened, convenient for storage and transportation, and have a large area of shelf display space, making it easier "Locking" the consumer's eyes and making it purchase intent. Flexible packaging technology can also bring considerable environmental benefits. It not only minimizes the waste of packaging contents, but also reduces the consumption of raw materials and increases the product-to-package ratio.

With the public's increasing awareness of reducing food waste and extending product shelf life, the demand for special barrier films for food flexible packaging has begun to show a continuous upward trend. Today, most barrier film products are often co-extruded through a blown film production line, commonly used in 7-, 9-, or even 11-layer film structures. Polyamide 6 has good barrier properties and mechanical strength and is an ideal material for the production of blown film grade food packaging films. However, the high crystallization speed of polyamide 6 limits its processing window. Therefore, processors need to make concessions in terms of production efficiency, or improve the processing performance by mixing polyamide 6 with special amorphous polyamide or polyamide copolymers, but this will make the film cost-effective advantages Great discount.
