Glue-penetration-free and fluffing-free cloth-plastic composite vacuum compression bag

Abstract

A bag opening of a bag body is provided with a sealing opening, the bag body is provided with an air valve, the bag body comprises an outer cloth layer and an inner film layer which are bonded and compounded through glue, and the two faces of the outer cloth layer are coated with PA coatings. The outer cloth layer coated with the PA layer is soft, smooth, waterproof and wear-resistant, and does not fluff after being used for a long time, so that the quality of the packaging bag is ensured; meanwhile, cloth holes of the woven cloth are blocked by the outer cloth layer coated with the PA layer, so that the problem of glue penetration when the woven cloth is compounded with the inner membrane layer is solved.

Description

Technical Field

[0001] The utility model relates to the field of vacuum compression bags, in particular to a non-adhesive and non-linting cloth-plastic composite vacuum compression bag. Background Art

[0002] At present, there is a kind of cloth-plastic composite bag in the market. The outer layer uses cloth as the main base material, which is bonded with the inner layer of PE plastic film by glue. The surface layer is soft and the quality is improved. The inner layer is airtight and has the effect of moisture-proof, mildew-proof and air-blocking for storing items. However, the cloth layer has pores, which will cause the problem of glue penetration, and the surface of the cloth layer will be fuzzy during use, which affects the appearance and use. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model provides an anti-glue and non-pilling cloth-plastic composite vacuum compression bag. The outer cloth is a woven cloth coated with a PA layer, which has good barrier properties. The outer surface layer will not pilose due to friction in use, and the finished bag will not pilose when the edges are sealed and cut. The viscose used for the composite of the inner and outer layers will not penetrate through the holes in the cloth. At the same time, the barrier properties and tensile strength are significantly improved.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The invention relates to a non-adhesive and non-linting cloth-plastic composite vacuum compression bag. The bag opening of the bag body is provided with a sealing opening, and the bag body is provided with an air valve. The bag body comprises an outer cloth layer and an inner film layer which are bonded and composited by glue, and the outer cloth layer is coated with PA coating on both sides.

[0006] A further improvement is that the PA coating on the outer fabric layer is coated with a water-repellent coating to prevent water from getting wet during use.

[0007] A further improvement is that the outer fabric layer is woven fabric.

[0008] A further improvement is that the inner film layer is a multi-layer co-extruded PE.

[0009] A further improvement is that the bag body is bonded and compounded using a single-component hot melt adhesive on a solvent-free compounding machine. Beneficial Effects

[0010] The outer fabric layer coated with PA layer is soft, smooth, waterproof and wear-resistant. It will not lint even in long-term use, and will not lint when the finished bag edges are sealed and cut, thus ensuring the quality of the packaging bag. At the same time, the outer fabric layer coated with PA layer blocks the holes of the woven fabric, solving the problem of glue penetration between the composite fabric and the inner film layer. The water-repellent coating of the fabric effectively prevents water from soaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In the figure: bag body 1, sealing opening 2, air valve 3; outer fabric layer 11, PA coating 12, inner film layer 13, water-repellent coating 14, adhesive layer 15. DETAILED DESCRIPTION

[0014] like Figure 1 , Figure 2 As shown, the utility model includes a bag body 1 having a sealing opening 2 at its bag mouth, an air valve 3 on the bag body 1, and the bag body 1 including an outer cloth layer 11 and an inner film layer 13. The outer cloth layer 11 is a woven cloth coated with a PA solution on both sides, and the woven cloth surface is dried and fixed to form a PA coating 12, and then the outer cloth with the PA coating is immersed in a solution containing fluorine, an emulsifier and water to coat a water-repellent coating 14, and then the outer cloth layer 11 with the double-sided PA coating and the water-repellent coating 14 is used as a substrate and bonded with the five-layer co-extruded PE inner film layer 13 on a solvent-free laminating machine using a single-component hot melt adhesive. Figure 2 Reference numeral 15 is a glue layer.

[0015] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
