Abstract
The utility model relates to a vacuum bag's seal structure of resistance to wears, close the layer including the sealing layer with scalding, the outside of scalding the layer of closing be the sealing layer, the outside of sealing layer be provided with the wearing layer. The utility model discloses simple structure has increased the wearing layer to can combine the sealing layer and scald the layer of closing together, improve the wearability of vacuum bag greatly, prevent to be damaged in the transportation.
Description
Technical Field
The utility model relates to a vacuum bag field especially relates to a vacuum bag's seal structure that resistance to wears.
Background
The vacuum bag is mainly used for preserving food, medicine, clothes and other articles, and the sealing performance of the vacuum bag is particularly important for improving the preservation quality. The traditional vacuum bag is mostly made of PA (nylon) + PE (polyethylene) materials in a combined mode, and the bag is easy to harden after vacuum pumping is finished, air leakage is caused due to various friction relations in the transportation process, the ideal effect cannot be achieved, and therefore the problem of abrasion resistance of the vacuum bag needs to be solved.
Disclosure of Invention
The utility model aims to solve the technical problem that a vacuum bag's seal structure that resistance to wears is provided, simple structure has increased the wearing layer to can combine the sealing layer and scald the layer of closing together, improve the wearability of vacuum bag greatly, prevent to damage in the transportation.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a wear-resisting seal structure of vacuum bag, includes the sealing layer and scalds the layer of closing, the outside of scalding the layer of closing be the sealing layer, the outside of sealing layer be provided with the wearing layer.
As a supplement to the technical proposal of the utility model, the wear-resistant layer is made of kraft paper or jean or cotton cloth material.
As a supplement to the technical solution of the present invention, the sealing layer is made of PA material.
As a supplement to the technical scheme of the utility model, the layer that closes that scalds adopt the PE material to make.
As a supplement to the technical scheme of the utility model, the sealing layer with scald the layer of closing and combine each other and form crowded membrane altogether.
And the wear-resistant layer and the sealing layer and the hot-melt layer are bonded by glue or hot melt.
Has the advantages that: the utility model relates to a seal structure that resistance to wears of vacuum bag, simple structure has increased the wearing layer to can combine the sealing layer and scald the layer of closing together, be a multilayer composite construction, workable needs vacuum state and surface have the sack and the packing of wearability, improved the wearability of vacuum bag greatly, prevent to damage in the transportation.
Drawings
FIG. 1 is a block diagram of the present invention;
fig. 2 is another structural view of the present invention.
Reference numerals: 1. wear-resisting layer, 2, sealing layer, 3, scald the layer of closing, 4, crowded membrane altogether.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1-2. The utility model discloses embodiment relates to a seal structure of resisting wearing of vacuum bag, close layer 3 including sealing layer 2 and boiling hot, the outside that closes layer 3 of boiling hot be sealing layer 2, the outside of sealing layer 2 be provided with wearing layer 1.
The wear-resistant layer 1 is made of kraft paper or jean or cotton cloth.
The sealing layer 2 is made of PA material, and the PA material is nylon, which is a common material with better sealing performance.
The ironing layer 3 is made of PE materials and mainly aims to play a role in bonding in the bag making process.
The sealing layer 2 and the hot-pressed layer 3 are mutually combined to form a co-extruded film 4, so that the number of layers of the vacuum bag is reduced.
And the wear-resistant layer 1 and the sealing layer 2 and the hot-melt layer 3 are bonded by glue or hot melt.
The wear-resistant layer 1 can improve the wear resistance of the vacuum bag and prevent the surface of the vacuum bag from being worn.
The utility model discloses simple structure, spare part is few, and to compressing tightly of valve block locking simple swift relatively moreover, the condition of gas leakage can not appear, has fine spreading value.
