Title:
シール適性である包装用の同時押出多層フィルム、その使用、およびその製造方法
Document Type and Number:
Japanese Patent JP4603532
Kind Code:
B2
Abstract:
The invention relates to a sealable, multilayer, coextruded packaging film with high transparency and high tensile strength. The film is composed of at least one core layer A made from a polyolefin with high tensile strength together with low elongation, and of outer layers B and C arranged on the two sides. The core layer A comprises from 50 to 100 % by weight of cyclic olefin polymer (COC) having a Tg of at least 60 ° C. The outer layers B and C may comprise at least one sealable polymer and one functional polymer. Intermediate layers may be arranged between layer A and layers B and C improving adhesion between layers. This film has a total thickness in the range from 20 to 200 mum, the core layer A making up from 5 to 60% of the total thickness of the film. The film is used in "flow-pack" packages produced on form-fill seal machines, or as a cover film on thermoformed blister packages or on cups (lidding).
