Abstract
Description
一実施形態では、積層フィルム10、柔軟包装材100、及び包装体40を作製するために、第1のステップにおいて、(任意選択的に、種々のレベルの結合親和性を有する)PSA13が、非接着剤区域27を残す所定のパターンでフィルム14とロールストック12との間に塗布されるとよい。代替的に、(任意選択的に、種々のレベルの結合親和性を有する)PSA13を非接着剤区域27を残す所定のパターンでフィルム14に塗布することによって、転写テープ11がオフラインで形成されてもよい。いずれの実施形態においても、次いで、フィルム14(又は、場合によっては転写テープ11)及びロールストック12が一緒に積層され、積層フィルム10を形成することになる。
図4〜図5は、本発明の包装体40の実施形態の斜視図である。柔軟包装体40は、(ロールストック12に接着されないように、フィルム14に形成された)単一プルタブ(図4)を引っ張ることによって、開封される。感圧接着剤13の接着の程度がわずかであることによって、再封可能なフラップ42がロールストック12から剥離する。更に具体的には、プルタブ22が持ち上げられると、フィルム14がオーバカット28に沿って離脱し、この時、PSA13を介してロールストックに付着していたフィルム14の部分が遊離する。このプロセスによって、包装体40の少なくとも1つの空洞29がアンダーカット44の存在に部分的に起因して開封され、この空洞29を介して、内容物にアクセスすることが可能になる。再封可能なフラップをめくることによって、すなわち、フィルム層14が取り去られ又はめくられる時に、ロールストック層12の一部を開くことによって、空洞29が現れる。このように、アンダーカット44は、包装体40の空洞29を画定しており、再封可能なフラップ42のオーバカット28の内側に形成されている。図4〜図5において、ユーザーが再封可能なフラップ42をめくることによって、(アンダーカット44によって画定された)空洞29が現れている。
