Embodiment Construction

[0016] First, the waterproof and breathable film is combined with the flame-retardant cloth to make the material for the packaging bag. According to the size of the object to be packaged, it is designed and cut into a rectangle or other shape of appropriate size. With the waterproof and breathable film as the inside, fold it in half to form a pocket shape. Both sides are bonded and sealed with self-adhesive; the other side is the mouth of the packaging bag. After putting the items to be packaged into the bag, glue and seal the bag mouth with self-adhesive; the width of the sealing edge is greater than 2mm; after bonding and sealing , Fold the three edges, and the width is still greater than 2mm. After the edge is folded, stick it firmly with self-adhesive, and the packaging is completed.

[0017] The use process of the packaging bag: the waterproof and breathable packaging bag made of a material composed of a waterproof and breathable film and a flame-retardant cloth is sealed ...

Abstract

The invention discloses waterproof breathable packing bag and the making methods. The packing bag is made of bond of waterproof breathable thin films and flame retardant fabrics by non-drying glue after compounding. The making method is that the waterproof breathable thin films and flame retardant fabrics are compounded to form the raw materials for making the packing bag and the raw materials are cut out in accordance with the size of the needed packing materials; the raw materials are folded with the waterproof breathable thin films as the inner and the non-drying glue is used to bond the seal edge into bag shape; the seal edge has width larger than 2mm and each seal edge is bonded again after folding. The packing bag of the invention has good waterproof breathable performance and can meet the requirement of the space and the relative waterproof breathable application of the ground, which is especially suitable for space breeding and has safe and convenient making method and good manufacturability.

Description

technical field [0001] The invention relates to the field of waterproof and breathable materials and their applications, and can be used for waterproof and breathable packaging in various fields, especially for spacecraft payloads such as a waterproof and breathable packaging bag required for space breeding and a manufacturing method. Background technique [0002] Waterproof and breathable material is a newly developed functional material. According to the different ways of waterproof and breathable, waterproof and breathable materials are also divided into many kinds. Considering the functional principle, according to different uses, they can be divided into: pore natural diffusion mechanism, microporous moisture permeability mechanism, "pore" between polymers and hydrophilic groups Moisture permeability mechanism, polymer temperature sensitivity changes moisture permeability, etc. Among these types of waterproof and breathable functional materials, functional materials wi...
