Problems solved by technology

[0003] Polyamide and polyethylene film are commonly used as vacuum packaging materials. Polyamide is commonly known as nylon. Nylon has good mechanical properties, but it is not easy to process, relatively hard, and the price is high. Polyethylene film material has relatively low strength and is also very soft. The elasticity is very good, but the mechanical properties, scratch resistance, etc. are not good
[0004] The current ordinary vacuum bag is made of a film, and the bag is evacuated by corresponding equipment. The ordinary vacuum bag is not tightly sealed, and does not have the corresponding flame retardant effect. At the same time, it is not sealed well during vacuuming. The packaging bag is not compressed, so that the air is easy to vacuum the bag after pumping, and loses the effect of vacuum sealing

[0037] Embodiment 1: a kind of glass fiber membrane, such as figure 1 As shown, it includes glass fiber cloth layer 1, flame retardant adhesive layer 2, PET layer 3 (polyethylene terephthalate film), first adhesive layer 4, aluminum foil layer 5, The second adhesive layer 6, the PA layer 7 (nylon), the third adhesive layer 8 and the SPE layer 9 (super functional PE film) with a thickness of 65 μm.

[0038]Among them, the glass fiber cloth layer 1 is 110g / m; the thickness of the PET layer 3 and the PA layer 7 are both 15 μm, and the thickness of the aluminum foil layer 5 is 9 μm; the first adhesive layer 4, the second adhesive layer 6 and the second adhesive layer The three adhesive layers 8 are acrylic adhesive layer, methacrylic adhesive layer, acrylate adhesive layer, epoxy resin adhesive layer, polyurethane composite adhesive layer, methacrylate adhesive layer, silicone modified Any one of the acrylate adhesive layers, and different types of adhesive layers can also be use...

Embodiment 2

[0045] Embodiment 2: a glass fiber vacuum bag, a glass fiber vacuum bag made of the glass fiber film in embodiment 1.

Embodiment 3

[0046] Embodiment 3: a kind of glass fiber vacuum bag making process among making embodiment 2 comprises the following steps:

[0047] S1, combine figure 2 As shown, the glass fiber membrane is folded in half to form a bag-like opening with the upper side 10, the lower side 11 and the left side 12, and one side of the glass fiber cloth layer 1 is the outer surface of the glass fiber vacuum bag.

[0048] S2. Carry out thermal bonding of the segmented hot-pressing module to the lower side 11 of the bag sample. The heating of the segmented hot-pressing module is symmetrically set, and the temperature in the middle is higher than the temperature on both sides; this scheme adopts a five-segment module Thermal bonding, and the temperature range is 150°C to 250°C, that is, the temperature of the modules from left to right is 150°C, 200°C, 250°C, 200°C, and 150°C.

[0049] S3. Carry out hot-pressing bonding to the left side 12 of the bag sample, and the hot-pressing temperature is 2...

Abstract

The invention discloses a glass-fiber membrane and a glass-fiber vacuum bag. According to the technical scheme, the glass-fiber membrane is characterized by comprising a glass-fiber cloth layer, a flame-retardant adhesive layer, a PET layer, a first adhesive layer, an aluminum-foil layer, a second adhesive layer, a PA layer, a third adhesive layer and an SPE layer which are sequentially connected from bottom to top. The glass-fiber membrane is prepared into the corresponding glass-fiber vacuum bag through a corresponding process, the prepared glass-fiber vacuum bag is good in sealing strength, compression strength and puncture resistance, and the sealing structural strength and usability of the glass-fiber vacuum bag are improved.

Description

technical field [0001] The invention relates to the technical field of composite membranes, more specifically, it relates to a glass fiber membrane and a glass fiber vacuum bag. Background technique [0002] Vacuum bags are also called decompression packaging. The main function of vacuum bags is to remove oxygen, so as to prevent the items inside from mildew and deterioration. Vacuum packaging bags are mostly used in food storage. The oxygen in the cell is sucked out by an air pump, so that the microorganism loses the "living environment" process. Vacuum bags can also prevent food from oxidizing, so that the food will not taste bad, and the deterioration will reduce the loss of vitamins. [0003] Polyamide and polyethylene film are commonly used as vacuum packaging materials. Polyamide is commonly known as nylon. Nylon has good mechanical properties, but it is not easy to process, relatively hard, and the price is high. Polyethylene film material has relatively low strength...
