摘要： Thermoformable plastic films can be formed into bags, pouches, trays, etc. which are useful when packaging foodstuffs and other products. These films enjoy widespread use in the packaging of meat and other oxygen sensitive products due to the gas permeation barrier provided. Thermoformable packaging films comprise one or more layers of thermoplastic, including olefinic copolymers, amorphous and crystalline nylons, ionomeric polymers, and polyolefins. By selecting the type and combination order of thermoplastics, a packaging film was developed that provides excellent impact and abrasion resistance, sealability, thermoformability, and optical clarity.

摘要： A packaged article, especially a respiring foodstuff such as cheese which generates or releases gas during storage, and a permeable multilayer biaxially oriented film suitable for allowing escape of such gas while minimizing transfer of oxygen across the film which has a thin layer of a blend of EVOH and nylon. In a preferred embodiment the low cost film having a high permeability to CO2 and low O2 permeability is used to package cheese.
摘要翻译： 包装制品，特别是在储存期间产生或释放气体的呼吸性食品如奶酪，以及可渗透的多层双轴取向膜，其适于允许这种气体逸出，同时最小化氧穿过膜的转移，所述薄膜具有薄层的混合物 EVOH和尼龙。 在优选的实施方案中，使用具有高的二氧化碳渗透性和低的O 2渗透性的低成本薄膜来包装干酪。
