Abstract
一种真空保鲜塑料袋，包括两张薄质膜体，膜体的两相对内表面均有凹坑，凹坑凹入方向为沿相对表面向外，且有规则排列，本实用新型在抽真空时，由于两相对内表面的凹坑彼此交错或相对，空气沿凹坑中间的间隙顺利排出袋外，在吸嘴周围不会形成吸附区，使得包装袋的真空度显著提高。
A vacuum fresh-keeping plastic bag, comprising two thin film bodies, the two opposite inner surfaces of the film bodies have dimples, the direction of the dimples is outward along the opposite surfaces, and they are arranged regularly. At the same time, because the dimples on the two opposite inner surfaces are staggered or opposite to each other, the air is smoothly discharged out of the bag along the gap in the middle of the dimples, and no adsorption area will be formed around the suction nozzle, so that the vacuum degree of the packaging bag is significantly improved.
Description
Technical field
The utility model belongs to a kind of vacuum freshness retaining plastic bag, particularly a kind of vacuum freshness retaining plastic bag made from composite material.
Background technology
The vacuum plastic bag that uses is made with the PE material usually at present, and permeability to air is very strong, even air also can enter after vacuum-packed a period of time, does not have fresh-keeping effect.Afterwards the someone to propose the material of plastic bag must be composite material, internal layer is non-poisonous PE or PP, outerly makes for sir-tight PA.Home-use vacuum bag sealer volume is little, power is low, therefore plastic bag integral body can not be put in the vacuum chamber and vacuumize, generally be open end to be put into vacuum chamber or to reach in the plastic bag to vacuumize with suction nozzle, when the common plane plastic bag vacuumizes, near near the suction nozzle (6), the upper and lower layer of plastic bag easily sticking and, form endless belt (7) (seeing accompanying drawing 4), endless belt rear portion air can not be drawn out of.
The utility model content
The purpose of this utility model provides a kind of vacuum packaging bag of two-layer composite, to improve the degree of vacuum in the packaging bag.
The utility model comprises two thin plasmalemmasomes, and two relative inside faces of film body all have pit.
The recessed direction of described pit is outside along opposite inner face, and the pit of two relative inside faces is interlaced with each other or relative.
Described film body comprises two-layer, and internal layer is made with the PE plastics, outer make with the PA plastics, with the internal layer skin compound after, be pressed into regularly arranged pit.
Claims (4)
1, a kind of vacuum freshness retaining plastic bag is characterized in that comprising two thin plasmalemmasomes, and two relative inside faces of film body all have pit.
2, vacuum freshness retaining plastic bag according to claim 1 is characterized in that, the recessed direction of pit is outside along opposite inner face, and the pit of two relative inside faces is interlaced with each other or relative.
3, vacuum freshness retaining plastic bag according to claim 1, it is two-layer to it is characterized in that film body comprises, and internal layer is made with the PE plastics, and skin is made with the PA plastics, after described internal layer skin is compound, is pressed into regularly arranged pit.
4, vacuum freshness retaining plastic bag according to claim 1 is characterized in that the pit size of each face is identical, and the distance between pit width and pit is according to the ratio setting.
