Abstract

The invention discloses an easy-tearing packaging film and a production process thereof. The easy-tearing packaging film comprises an external layer film, a middle layer film and an internal layer film; the external layer film employs linear low density polyethylene and low density polyethylene as raw materials; the middle layer film employs linear low density polyethylene and low density polyethylene as raw materials; the internal layer film employs polypropylene and an anti-blocking and slipping agent as raw materials. Heat-sealing is carried out for the easy-tearing packaging film, film heat-sealing strength is 5-15N / 15mm, and during tearing, peel strength fluctuation is equal to or less than 3N / 15mm; the film has smooth handfeel without pause, and phenomenon such as layering, peeling, breakage, drawing of residual glue and the like does not exist.

Description

technical field [0001] The invention relates to the field of packaging films, in particular to an easy-to-open packaging film for food and a production process thereof. Background technique [0002] In the current snack food market, most of them open the food packaging bag by tearing the tear on the packaging bag, and then taste the food in the packaging bag. However, these packaging bags with tear openings are not suitable for some smaller foods. When the bag is torn open through the tear opening, because the bag shape of the packaging bag is small, it is difficult for consumers to handle and it takes a lot of effort, and it is difficult to control the strength. If the food is a paste-like solid, once the force is too strong, it will cause the liquid to splash out or even the contents to fly out, which will have a negative impact on the consumer's experience with the product. [0003] Therefore, this technology needs further improvement and development. Contents of the ...
