Abstract
The invention discloses a deformation-preventive high-elasticity material for a bag inner and a preparation method of the material and belongs to the field of packaging supplies.The deformation-preventive high-elasticity material comprises EVA, TPR, TPE, PE, filler, catalyst, foamer, antioxidant and processing aid.The preparation method includes: mixing above materials well in an internal mixer according to a certain proportion; adding the foamer for mixing and discharging; fusing and mixing in a double-screw extruder; using a header for extruding, drawing, air-cooling, sized-slicing and drying to obtain a final product.After various chemical raw materials are added into synthetic plastic, the plastic has higher elasticity, sealability and wear resistance.The high-elasticity material is used as an inner material of a handbag and used for supporting outside leather, original design shape of the handbag can be maintained, and the handbag can restore the original shape even after being pressed or twisted and does not deform after being used for a long time.
Description
Technical field
The invention belongs to package packing supplies field, more particularly, it relates to high-elastic material of body anti-deformation and preparation method thereof in a kind of bag.
Background technology
Liner in product package material, primarily serves the effect of buffering, protection product.Existing relatively common inner liner portion probably has:
1.PS, PVC (flocking) blister plastic packaging liner；Although plastic uptake technique plastotype is perfect, technical maturity separately has plus flocked surface attractive in appearance to increase, but PS, PVC sheet suction plastic lining is more crisp frangible, lower thickness after the product that plastic uptake is deep, it is easy to deformation.
2.EPS note type pad face cloth package lining；According to packed article shape profile foaming, but rough, and EPS is made up of individual particle shape, being easy to fragmentation, it is impossible to enough exposed, needing to cover a shell fabric on surface under normal circumstances increases attractive in appearance, but not docile after covering fabric, lose the profile of product.
3.EVA shape by die-cutting package lining；It is the face profile shape by die-cutting according to product, but can only be the profile of plane, and cross cutting cannot mould three-dimensional contouring, and expensive packed article volume highlights the die-cut value waste abandoning part time bigger.
4.EVA engraves milling molding package lining；CNC engraving technology is used to carve, solving EVA shape by die-cutting package lining cannot the shortcoming of three-dimensional contouring, but the limitation due to technique, production cost is expensive, the production capacity metal working process also having Water Cutting, line cutting etc. ripe little, similar can be applied, but all cannot reduce cost and increase production capacity.Additionally also have the package lining of the various ways such as relatively common papery liner, though cheap, there is no class, almost without buffering effect.
Being commonly used in handbag the material of body in prior art is cloth, and simple being used for separates mutually with leather, as interior trim and the purposes putting article, does not play other effects.And body material is distorted in common handbag, be squeezed not resilient, and not only impact uses next time, increases operation cost, and the article protection in handbag is limited, has an effect on attractive in appearance after distortion.
In order to solve the problems referred to above, it is badly in need of a kind of high resiliency anti-deforming material packing body in product, urgently high-elastic material of body anti-deformation and preparation method thereof in a kind of bag.
