Abstract

The present invention relates to a plastic wrap and a plastic wrap dispenser thereof. The plastic wrap comprises a plurality of preset tear structures, and the plurality of preset tear structures areconfigured on a single edge or two opposite edges of the wrap film, which benefits the plastic wrap to be torn off. In addition, the plastic wrap contains a polymer having linear tearing property, sothat when the plastic wrap can be torn straightly. The plastic wrap dispenser includes a box, a cutter, and the plastic wrap of the present invention, wherein cutter of the plastic wrap dispenser is ashort cutter or a retractable cutter, which benefits the user from being finger cut when using the plastic dispenser.

Description

technical field [0001] The present invention relates to a kind of plastic wrap and its plastic wrap box group, especially a kind of plastic wrap with linear tearability and easy to tear, and the plastic wrap box group used with it is not easy to cut fingers. Background technique [0002] If the food is put directly into the refrigerator, it is easy to make the refrigerator produce peculiar smell, and it may also absorb the smell of the refrigerator, especially the starchy food is easy to absorb the peculiar smell in the refrigerator. In order to keep food fresh, modern people use plastic wrap to package food and then put it in the refrigerator, so that the food is not easy to deteriorate and the storage time is prolonged. Therefore, plastic wrap is one of the indispensable kitchen supplies for families now. [0003] The material of the plastic wrap needs to have properties such as heat resistance, ductility, and elasticity. Among them, good heat resistance can not only seal...
