PA/EVOH Based Thermoforming Films for Food Packaging

PA/EVOH Based Thermoforming Films for Food Packaging

Thermoforming is a plastic forming process that creates a wide variety of consumer products by melting plastic sheets on a mold and cooling them. Thin plastic sheets used to produce thin plastic parts are called thermoformed films.

11 layers Casting PA/EVOH Based Thermoforming Film is a method of forming plastic sheets. Depending on the product type, these sheets are available in a variety of thicknesses. The thinner plastic sheet is called a film. Thermoformed films are essential for the production of many common consumer products.

Some of the advantages traditionally associated with PA/EVOH Based Thermoforming Film

Low cost          Plastic forming film is an affordable raw material, and the thermoforming process facilitates mass production, generating additional economies of scale in     mass production.

Versatility        Thermoforming film is a flexible process that can be used to manufacture plastic products of varying complexity.

Low waste       Excess material can be collected, remelted, regranulated, and formed into plastic films for additional thermoforming activities.

Application for coextruded high barrier PA/EVOH Based thermoforming films

Consumables                             Thermoformed films are often the preferred method for manufacturing single-use plastic cups, plates, and other consumer goods.

Daily necessities packaging        Thermoformed films are used to make plastic packaging for products in retail, medical, food and beverage, and other industries.

Medical packaging                     Thermoformed films can be used to pack masks or other medical supplies accessories.

Monitor screen                           The screens on many smart devices are made from thermoformed films.

Vacuum                                     Creating a vacuum between the heated sheet and the mold cavity pulls the pliable sheet into the mold, forcing it to form to the mold’s various details. 

Pressurized                                This method adds additional force to the vacuum technique by applying additional pressure against the sheet to push it into the mold. This additional pressure is created using compressed air.

Mechanical                                 Mechanical thermoforming uses a mated box to push the plastic sheet down into the mold. 

Vacuum thermoforming is the most common method for films, as thinner material doesn’t require excess pressure to form tightly to the mold. Once the plastic sheet is heated and formed to the mold, it is allowed to cool and undergo cutting and other secondary processes to form the final product.
