It is reported that European thermoforming processors are keen to use thermoplastic foamed polystyrene materials for fresh meat packaging, and polypropylene packaging materials will gradually be eliminated in the market.

Polypropylene packaging has been used for a long time due to its low cost and durability. However, such containers have a variety of disadvantages, such as poor stability of the package when heated, obscuring sealing films, poor transparency, and slow filling speeds during processing. The foamed polystyrene has excellent processing properties and can well accept polyethylene or polyvinyl chloride film as an outer film, and has excellent gas barrier properties. The disadvantage is that the high temperature stability is poor, and because of the thickness standard of 3 mm, it cannot be made into a box with a steep wall angle.

The European company LINPAC, which has a history of more than 80 years in the thermoplastic molding market, has developed anti-theft foamed polystyrene packaging boxes and foamed polystyrene packaging boxes for microwave ovens. It is firmly believed that these innovative products will replace polypropylene in meat in the future. Food packaging applications.
