Embodiment Construction

[0030] Below in conjunction with embodiment the present invention is described in further detail.

[0031] see figure 1 , 2, the present invention relates to a kind of preparation method of fresh food thermal insulation and environmental protection express packaging bag, described packaging bag comprises the bag body 1 that is used for accommodating articles, and one side of described bag body 1 has bag opening, and in A flange 2 that can close the mouth of the bag is formed at the mouth of the bag, and an adhesive tape 3 is pasted on the flange 2. The two sides of the bag body 1 are sewn by ultrasonic waves. The bag body 1 is made of a protective film 1.1 and a non-woven fabric. The cloth core material 1.2 is composed of the non-woven fabric core material 1.2 wrapped in the protective film 1.1, the protective film 1.1 at the mouth of the bag is sealed by a hot-melt sealing machine, the protective film 1.1 on both sides of the bag body 1 and the non-woven fabric core material ...

Abstract

The invention relates to a fresh food insulation environment-friendly express packing bag and a preparation method thereof. The packing bag consists of a protective film and a non-woven fabric core material; and the non-woven fabric core material is coated in the protective film. The method comprises the steps of: (1) fiber processing; (2) non-woven fabric processing; (3) PLA protective film processing; (4) non-woven fabric slicing; (5) coating of the non-woven fabric in the protective film; (6) protective film bag sealing; and (7) packing bag production. The packing bag can effectively reduce the consumption of woods and petrochemical materials, and prevents the imbalance of a natural ecological system and the pollution and the damage to the environment by chemical materials; and meanwhile, the non-woven fabric is adopted as the core material to effectively preserve heat of fresh foods.

Description

technical field [0001] The invention relates to environmental protection product technology, in particular to a fresh food express heat preservation structure and a disposable fully degradable packaging bag. Background technique [0002] Currently commonly used polyethylene (PE) and polypropylene (PP) plastic packaging bags are widely used in people's daily life due to their light weight, low price, and convenient use. However, while it enriches and facilitates people's lives, it causes serious "white pollution" problems because its main components are difficult to decompose in the natural environment. With the sustainable development of society, ecological environment issues have been raised to the height of development strategy by governments of all countries. [0003] At present, there are four main ways to propose degradable packaging at home and abroad: (1) products using starch as a binder; (2) double-degradable plastic products characterized by biodegradation and pho...
