Abstract
The invention provides an inflating buffer packaging body and a processing method thereof. A buffer effect is well provided, and meanwhile, the air rightness performance of a sealing body is improved. The inflating buffer packaging buffer adopts a structure comprising two outer films and one inner film, and the structure comprising one inner film is adopted, so that the effect of adopting a resin film with the thickness of the two inner films as an air locking device becomes possible, when the thickness is doubled, the ventilation rate is halved, in addition, a multilayer co-extrusion resin film with higher blocking performance is adopted to be used as the inner film, the ventilation rate is lower, and ink coats the inner film every a period of distance; a transverse hot sealing line for realizing the hot sealing on the inner film and the outer films spans across the ink, and an air passage is formed at the ink part; an air inlet passage is formed in a plurality of air storage spaces on the inflating buffer packaging body by points or lines through hot sealing, the air inlet passage is communicated with an ink air passage, and the distance of the air inlet passage is preferably 4mm to 15mm. The inflating buffer packaging body has the advantages that a protection effect can be achieved on a product for a long time, the air can be stored in the films for a long time, the processing is convenient, and the sealing is reliable, so that the environment-protection package can be favorably and widely applied.
Description
Technical field
The invention belongs to packing technique field, be specifically related to a kind of inflation cushioning package body and job operation thereof.
Background technology
Inflation buffering package take resin molding as material, after inflation, air containment plays the device of buffer action in resin molding, common aeroseal body structure as Japanese Utility Model Beneficial No. JP5-95851 (fluid sealing bag) Patent Case, U.S. patent Nos US7568508; No. TW00587049th, Taiwan patent of invention (installation constitution of the switch valve of sealing member and there is the manufacturing installation of sealing member of switch valve); No. TW92113574, TaiWan, China patent discloses a kind of installation constitution of switch valve of sealing member; And patent of invention CN200610067311.5, CN200910128472.4, CN201010286239.1 etc. are about the method for making of sealing member, the common ground of above-mentioned patent is the structure using two panels adventitia and two panels inner membrance, and heat proof material is applied as free air diffuser between two panels inner membrance, and utilize two panels inner membrance to play the effect of lock gas, shown in Figure 2.
The shortcoming that the structure of above prior art is maximum must use two panels inner membrance exactly, because the length of inner membrance and adventitia can not be isometric, so inner membrance is too thick will increase heat-sealing difficulty of processing, the too high meeting of temperature scorches the part only having adventitia not have inner membrance, the part that temperature is too low a two panels adventitia two panels inner membrance again can not good heat-sealing, but also can increase material cost.Particularly now those PP TYPE with high barrier are not used due to the problem of thickness on original design plan; thinner resin molding so just can only be used to make two panels inner membrance; because inner membrance is the effect playing lock gas; just high with thinner film permeability to air; just be unfavorable for this kind of long-term article of packaging are played a protective role of buffering package, thus also just have influence on extensive popularization and the utilization of this kind of environmental protection buffering package.
Therefore, prior art lacks a kind of inflation cushioning package body, and it can be convenient to processing, while providing buffer action well, also can improve the performance of holding one's breath of sealing member.
Summary of the invention
For above-mentioned one or more problems, provide a kind of inflation cushioning package body and job operation thereof, it is convenient to processing, while providing buffer action well, also can improve the performance of holding one's breath of sealing member.
The present invention adopts two panels adventitia, the structure of a slice inner membrance, and as shown in Figure 1, efficiently solve the defect of original design plan, air can be preserved for a long time in film.Further; owing to being the structure of a slice inner membrance; thus relatively thick inner membrance can be adopted; the resin molding of the thickness of preferred use two panels inner membrance is as air-lock device; due to thickness double permeability to air reduce half; the multi-layer co-extruded resin molding of high barrier preferably can also be adopted to do inner membrance; permeability to air can be lower; in addition; preferred inner membrance and be intermembranously designed with viscosity outward; more promote lock airway dysfunction, like this this kind of inflation buffering package just permanent product played a protective role of energy, thus this type of environmental protection package just can be promoted and be utilized widely.
