Description

Degradable packaging film

Technical Field

The utility model relates to the technical field of packaging films, in particular to a degradable packaging film.

Background

The plastic package bag is a high molecular compound made of monomers as raw materials through polyaddition or polycondensation reaction, and is generally made of synthetic resin and additives such as filler, plasticizer, stabilizer, lubricant, pigment, etc. In daily life of people, plastic packaging bags are widely applied, but white pollution caused by waste plastics is more and more serious. With the enhancement of environmental awareness of people, how to alleviate white pollution is an increasingly concerned topic. The degradable plastic packaging bag is a new plastic product in recent years, all the properties of the degradable plastic packaging bag can meet the use requirements, the degradable plastic packaging bag has the characteristic of unchanged performance in the preservation period, and the degradable plastic packaging bag can be degraded into substances harmless to the environment under the natural environment condition after being used, so that the degradable plastic packaging bag is widely welcomed by people.

Current food packaging film when using, need tear from the spool above, tear the mouth after tearing irregularly, be not convenient for pack next time, secondly, the film when packing article, does not have the banding structure to make article can expose in the air for a long time, than being convenient for to the storage of article, in order to solve the not enough of current packaging film in the use. To this end, we propose a degradable packaging film.

SUMMERY OF THE UTILITY MODEL

The present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a degradable packaging film.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a degradable packaging film, includes the stay tube, the stay tube both sides all are equipped with the baffle, be equipped with the film body on the stay tube, the film body includes a plurality of main packaging film, and is adjacent be equipped with the crease between the main packaging film, the crease both ends all are equipped with the bell mouth, be equipped with the through-hole that a plurality of equidistance were arranged between the crease, main packaging film surveys and is equipped with vice packaging film, main packaging film keeps away from vice packaging film one end and is equipped with bonding portion.

Preferably, the secondary packaging film is provided with a frosted part matched with the bonding part at one end close to the bonding part.
