Abstract
The utility model discloses a multi-layer compound net-type drying agent packing paper, which is composed of a base paper layer which is the surface layer, a plastic film layer which is middle layer and a plastic net layer which is the bottom layer, the three layers are compounded; the plastic film layer is provided with air holes, the plastic net layer is a hot melt plastic compound cross net, and the base paper layer, the plastic film layer and the plastic net layer adopt hot melt compound adhesion. The utility model has high strength, fine air permeability, and prevents foam being leaked and can be printed; moreover, the packing paper has heat-seal function, meets food packing sanitary requirements and is primarily applied to pack drying agent, anti-staling agent and oxygen scavenger.
Description
Technical field
The utility model relates to a kind of packing, especially relates to a kind of desiccant packing of MULTILAYER COMPOSITE.
Background technology
That the packing material of desiccant requires is ventilative, in the regular hour moisture absorption and must not leak the end, and have higher-strength.The packing of the desiccant that uses at present have three kinds: the nonwoven fabrics that make as raw material with meldable fibre (1); (2) paper plastic combined package paper; (3) wrapper of making by paper, nonwoven fabrics, glue and plastic layer.
Nonwoven fabrics is a single layer structure, has certain heat sealability, and cost is low, but leak tightness is poor, and easily the moisture absorption, leakage end only are applicable to desiccant such as packing silica gel, generally are not suitable for the food desiccant packing.
Paper plastic combined package paper is composited with plastics for copied into paper (abbreviation body paper) by vegetable fibre or chemical fiber, is double-decker.For being suitable for gas permeability requirements, adopt the ventilative processing of needle point method, material is pierced.Because the intensity of body paper and plastics is not too high, after the ventilative processing of needle point method, the integral material intensity difference, the easy moisture absorption, leakage end, service life is short, generally is not suitable for to pack powdery type desiccant.
By the wrapper that paper, nonwoven fabrics, glue and plastic layer are made, be to fit with glue earlier by body paper and nonwoven fabrics, compound one deck plastic film on the nonwoven cloth cover again, the processing of breathe freely of last needle point method is made.This material has higher intensity owing to adding layer of non-woven fabric, but fails to solve the problem at the moisture absorption, leakage end.
Summary of the invention
The utility model provides a kind of net type desiccant package paper of MULTILAYER COMPOSITE, its intensity height, good permeability, does not leak the end, can print, and has heat sealability.
The utility model is made up of for three layers top layer original paper layer, interlayer plastic membranous layer and bottom plastics stratum reticulare, and is compound mutually, has breather hole on the plastic membranous layer.
Described plastics stratum reticulare is the compound crossing net of hot-melt plastic.
Original paper layer, plastic membranous layer, plastics stratum reticulare three are the hot melt compound sticking layer by layer.
The utility model is compared with existing product, has following outstanding feature: outer paper has printing, permeability to air, oil resistant, moisture-proof, has certain wet strength, can prevent that the powder-type desiccant is to external leakage.Plastic membranous layer is sandwiched between outer body paper and the plastic wire, impels body paper and net mortise, and plays heat sealable effect, have breather hole on the plastic membranous layer, have higher permeability to air, plastics stratum reticulare and plastic membranous layer hot melt are compound, and net structure increases integral material intensity greatly.Therefore the utlity model has higher-strength, anti-broken anti-tearing can prevent dust leakages such as desiccant, and have heat sealability when having permeability to air, meet the packaging for foodstuff hygienic requirements, is mainly used in the packing of desiccant, antistaling agent, deoxidizer.Desiccant, antistaling agent, deoxidizer with the utility model is packed can be widely used in industries such as food, medicine, clothes, footwear, mechanical electronic equipment, electronic machine, instrument.
Description of drawings
Fig. 1 is a cross-section structure enlarged diagram of the present utility model.
The specific embodiment
As figure, the utility model is made up of three-decker, and the top layer is an original paper layer 1, and interlayer is a plastic membranous layer 2, and bottom is that 4, three layers of plastics stratum reticulares adopt that to drench the three-in-one hot melts of membrane process compound, carries out permeability to air after compound and handles to make and have breather hole 3 on the plastic membranous layer 2.
The utility model technological process of production: the body paper printing → → rewinding → → body paper, plastic film, the three-in-one pouring film of plastic wire be compound → → permeability to air handles → → cut → → product inspection → → packing.
Hp-ldpe was generally selected in the effect of heat-sealing for use when body paper required to have certain intensity and bursting strength, plastic film mainly to play laminated effect of pouring film compound tense and packing.Plastic wire is the hp-ldpe crossing net, works to guarantee product strength in the utility model, adopts and drenches membrane process, makes three layers of hot melt compound.
Claims (3)
1. net type desiccant package paper is characterized in that: forms for (4) three layers by top layer original paper layer (1), interlayer plastic membranous layer (2) and bottom plastics stratum reticulare, and compound mutually, have breather hole (3) on the plastic membranous layer (2).
2. a kind of net type desiccant package paper according to claim 1, it is characterized in that: described plastics stratum reticulare (4) is the compound crossing net of hot-melt plastic.
3. a kind of net type desiccant package paper according to claim 1 is characterized in that: described original paper layer (1), plastic membranous layer (2), plastics stratum reticulare (3) three are the hot melt compound sticking layer by layer.
