Description
Technical field
This utility model relates to packaging field, is specifically related to a kind of packaging bag.
Background technology
Packaging bag refers to the sack for packing various articles for use, makes goods convenient transport in producing the process of circulation, it is easy to storage, is widely used in daily life and commercial production.Packaging bag as packing liquid, semifluid, powder body etc., it is proposed that the multiple film constituted by overlapping multiple films is formed as bag-shaped packaging bag.For this packaging bag, the film constituting multiple film is disengaged condition each other on a large scale, can break away each other in the region of this disengaged condition.Part membrane structure is provided with aluminum membranous layer, but in use, this aluminum membranous layer is owing to being subject to External Force Acting, easily produce folding line or fracture, largely effect on its barrier property, thus reducing whole service life, and existing packaging bag is in use, the phenomenon causing packaging bag damaged because the impulsive force of junction is more weak, bearing capacity is poor often occurs.There is the problems such as overall impact resistance is poor, and toughness is not enough, and sealing is undesirable with barrier property in existing packaging bag.For solving the problems referred to above, this utility model provides one to seal firmly, and bearing capacity is strong, the packaging bag of long service life.
Utility model content
This utility model provides a kind of packaging bag, seals firmly, and bearing capacity is strong, the packaging bag of long service life.In order to realize above-mentioned technique effect, this utility model adopts the following technical scheme that
A kind of packaging bag, including bag body and bag back cover, described bag body is made up of a tubular packaging bag thin film one, described packaging bag thin film one includes four-layer structure from the inside to the outside, it is followed successively by PE thin film, nylon layer, aluminum film, PET film, described bag body is formed by sealing bar sealing, described bag back cover is cut in a circle by packaging bag thin film two, described packaging bag thin film two includes four-layer structure from the inside to the outside, it is followed successively by PE thin film, nylon layer, aluminum film, PE thin film, is connected by two heat-sealing bars between described bag body and described bag back cover.
A kind of packaging bag that this utility model provides, it is also possible to be further arranged to two described heat-sealing bars and be arranged on the inner surface of described bag back cover.
A kind of packaging bag that this utility model provides, it is also possible to the spacing being further arranged to two described heat-sealing bars is set to 1-5 millimeter.
A kind of packaging bag that this utility model provides, the surfaces externally and internally that can also be further arranged to an end margin of the junction of described bag body is equipped with described heat-sealing bar, the two ends inner surface of described bag body is sealed by described heat-sealing bar, and the outer surface of described bag body is outwards sealed by described heat-sealing bar.
A kind of packaging bag that this utility model provides, it is also possible to be further arranged to described bag and be provided with air valve.
Advantage of the present utility model and having the beneficial effects that: to sum up, a kind of packaging bag that this utility model provides, described bag body adopts described packaging bag thin film one, described bag back cover adopts packaging bag thin film two, by adjusting glued construction, sealing place and the described bag body that make described bag body seal more firm with the junction of described bag back cover, strengthen the bearing capacity of packaging bag.Wherein:
1. described in, packaging bag thin film one includes four-layer structure from the inside to the outside, it is followed successively by PE thin film, nylon layer, aluminum film, PET film, described packaging bag thin film two includes four-layer structure from the inside to the outside, it is followed successively by PE thin film, nylon layer, aluminum film, PE thin film, two described heat-sealing bars are arranged on the inner surface of described bag back cover, the spacing of two described heat-sealing bars is set to 1-5 millimeter, the PE thin layer of described bag body is made to seal with the PE thin layer of described bag back cover, strengthen the firm intensity of sealing of described bag body and described bag back cover junction, improve the bearing capacity of packaging bag, increase the service life, increase operation rate.
2. the surfaces externally and internally of an end margin of the junction of bag body described in is equipped with described heat-sealing bar, the PE thin layer making two ends, the junction inner surface of described bag body seals mutually, the PET film layer of two ends, the junction outer surface of described bag body seals mutually, enhance the sealing strength of the junction of described bag body, improve the impulsive force of described bag body, extend the service life of packaging bag.
3. it is provided with air valve with bag described in, prevents the air outside packaging bag from entering packaging bag during use, it is ensured that the quality of product in bag.
