| 摘要 |
<p>The present invention is related to a flow pack comprising a peelable film, said film comprising a coextruded multilayer structure, said structure comprising:
- a rupturable polyester-based inner sealant layer (1);
- an adhesive layer (2) in contact with said rupturable layer, comprising a polymer selected from the group consisting of ionomers, maleic anhydride grafted polyolefin, EVA, EBA, EMA and EAA;
- a gas-barrier layer (3) in contact with said adhesive layer (2), comprising a gas-barrier polymer selected from the group consisting of polyester, EVOH and polyamide,
- an outer sealant layer comprising a polymer selected from the group consisting of amorphous polyester, copolymer of PET, and polyvinyl chloride,
characterised in that the average peel strength (10) between the adhesive layer (2) and the inner sealant layer(1) is lower than 15N/15mm, preferably lower than 13N/15mm as measured in a 180° peel geometry.</p> |
