Film for packaging and packaging bag

Abstract

Provided is a film for packaging, when an object is placed at the center of the film, wrapped by twisting the ends of the film above the object and then allowed to stand for a preset period of time, said film being capable of retaining the twisted state and thus preventing the diffusion of an offensive smell. The film according to the present invention is characterized in that the film is a film for packaging that is formed of a resin film and has a twisting retention angle of 400 degrees or greater.

Description

technical field [0001] The present invention relates to a film for packaging and a packaging bag capable of suppressing diffusion of odor. Background technique [0002] When an object is covered with a polyethylene film, the fragrance retention (odor suppression effect) of the film itself is not sufficient, and when the object covered by the film has a strong odor, the odor will leak through the polyethylene film. On the other hand, polyester film has fragrance retention, and the odor is not easy to pass through the film. For example, like the polyester film of Patent Document 1, there is known a film that has twistability to some extent even after it is twisted and packaged and left to stand for a certain period of time. [0003] However, in the polyester film of Patent Document 1, when an object is placed in the center of the film to cover it, and the object is twisted and placed for a certain period of time, the twistability is not sufficient, so the twisted portion has ...

AI Technical Summary

Problems solved by technology

[0003] However, in the polyester film of Patent Document 1, when an object is placed in the center of the film to cover it, and the object is twisted and placed for a certain period of time, the twistability is insufficient, so the twisted part has a slight opening, and the film-wrapped When the object has a strong odor, the odor will leak out

In addition, when the object to be wrapped with a film is large, it is conceivable to use a bag-making film, but the polyester film in Patent Document 1 has a high melting point, so it is not possible to directly bond the polyester films to each other by heat sealing. It is necessary to install a sealing layer on the inside, etc.
