transparent colorless food grade rigid pvc film food grade
Transparent colorless food - grade rigid PVC film is a type of plastic film that is widely used in the packaging industry, especially for thermoforming applications.
This kind of film is made from polyvinyl chloride (PVC) resin and is characterized by its high transparency, allowing for good visibility of the packaged food products. It is colorless, which ensures that it does not impart any color to the food or affect its appearance. Being food - grade, it meets strict safety standards, such as those set by the EU regulations, ensuring that it does not release harmful substances when in contact with food.
The rigid nature of the film provides good structural support, making it suitable for thermoforming processes. During thermoforming, the film can be heated and shaped into various forms, such as trays, blisters, and containers, to package different types of food items. It has good dimensional stability, meaning that the thermoformed parts are not easy to shrink or deform after cooling. Additionally, it has excellent mechanical properties, including sufficient tensile strength and elongation, which facilitate the thermoforming process and ensure the integrity of the final packaging product.
Common Uses of Transparent Colorless Food-Grade Rigid PVC Film in Thermoforming
Transparent colorless food-grade rigid PVC film is widely favored in the thermoforming packaging field due to its excellent transparency, food safety compliance, rigid structure, and good thermoforming adaptability. Its common applications mainly focus on the packaging of various food products that require visibility, protection, and convenient storage or transportation. The specific uses are as follows:
1. Fresh Food Packaging Trays
This is one of the most common applications. Thermoformed trays made from this film are widely used for packaging fresh meats (such as pork, beef, and chicken), aquatic products (such as fish, shrimp, and shellfish), and fresh poultry. The high transparency of the film allows consumers to clearly observe the appearance, color, and freshness of the internal food, enhancing purchase confidence. Meanwhile, the rigid structure of the film provides good support and protection, preventing the food from being crushed or deformed during transportation and display. In addition, the food-grade material ensures no harmful substances are released, meeting the safety requirements for direct contact with fresh food.
2. Snack and Confectionery Blister Packaging
It is commonly used for thermoforming blister packaging of various snacks and confectioneries, such as potato chips, nuts, candies, chocolate, and biscuits. The thermoformed blisters can be customized into different shapes and sizes according to the product specifications, tightly wrapping the snacks to isolate them from air, moisture, and external pollutants, thereby extending the shelf life of the products. The transparent feature enables consumers to directly see the product style and quantity, which is conducive to product display and promotion. Moreover, the rigid film makes the blister packaging not easy to be damaged, ensuring the integrity of the snacks during circulation.
