Title (EN) STRETCH PACKAGING FILM WITH EASY TEAR FUNCTION
(FR) FILM D'EMBALLAGE ÉTIRABLE À FONCTION DE DÉCHIRURE FACILE
(ZH) 一种具有易撕功能的拉伸包装膜
Abstract:
(EN) Disclosed is a stretch packaging film with an easy tear function, comprising a cast polypropylene film (1), a polyvinylidene chloride film (2) and a polyethylene co-extruded film (3) sequentially stacked and laminated from top to bottom, wherein each two adjacent layers are bonded together by means of a glue layer (4). By using a composite stretch film to replace a co-extruded stretch film, a consumer can open the package with a small force when using same, thus improving the consumption experience of the consumer.
(FR) L'invention concerne un film d'emballage étirable avec une fonction de déchirure facile, comprenant un film de polypropylène coulé (1), un film de polychlorure de vinylidène (2) et un film co-extrudé de polyéthylène (3), qui sont empilés et stratifiés séquentiellement de haut en bas, chaque deux couches adjacentes étant liées ensemble au moyen d'une couche de colle (4). En utilisant un film étirable composite en vue de remplacer un film étirable co-extrudé, un consommateur peut ouvrir un emballage avec une faible force lors de l'utilisation dudit film, ce qui permet d'améliorer l'expérience de consommation du consommateur.
(ZH) 一种具有易撕功能的拉伸包装膜,包括由上至下依次叠放贴合的流延聚丙烯薄膜(1)、聚偏二氯乙烯薄膜(2)和聚乙烯共挤膜(3),相邻两层之间通过胶水层(4)粘接在一起。使用复合拉伸膜,取代共挤拉伸膜,消费者在使用时只需要很小的力,就可以开启包装,提高消费者的消费体验感。
