Abstract
The utility model relates to sheeting applied to package of food and medicine, which belongs to food package section bar, and discloses that middle part of the sheeting applied to package of food and medicine is a separation layer; after being bonded with a basilar membrane layer through a bonding layer, two sides of the separation layer constitute high separation composite sheeting applied to package of food and medicine. The separation layer is EVOH or EVOH polymer layer; the bonding layer is maleic anhydride grafting copolymerization layer; the basilar membrane layer is an HIPS layer. The preparation method thereof is to employ a three-machine five-layer co-extrusion extruder and input fusion of HIPS, bonding agent and EVOH in proportion to synthetize a die head which is extruded from a die orifice; HIPS and EVOH are tightly bonded through bonding resin, which is extruded to form a high separation multi-layer co-extrusion sheeting under the effect of tractive force through mechanical effect of a roller. The sheeting applied to package of food and medicine can effectively separate passage of oxygen and the like of gas, maintain perfume of the content for a long time, and separate influence from outside gas to the content; the sheeting applied to package of food and medicine is easy to be heated for fabricated operation, pro-environment and nontoxic, and is suitable for quality and refreshment guaranteeing, as well as oxygen isolation and water proof package of various proper objects like food and medicine.
Description
Technical field
The utility model relates to packaging for foodstuff section bar, particularly food, drug packaging multi-layer coextrusion laminated materials with high impedance.
Background technology
Along with the development of producing, high barrier has become one of important development direction of plastic package material, especially in food, medical packaging, more and more emphasizes high barrier especially.Industrialization at present or the barrier material with suitability for industrialized production prospect mainly contain PVDC, EVOH, PEN, itrile group resin, polyamide etc.PVDC is because of the restriction of its material character, and prior art adopts mostly and applies and film-blowing process production, makes its purposes receive restriction greatly.Coating processes will use glue bonding when producing because of it, so the coating phenomenon is fallen in as easy as rolling off a log in use generation, has certain security risk, and recycles to be worth and reduce.EVOH resin barrier property is better than PVDC, and is easy to forming work, but because hygroscopic property is big, relative humidity was greater than 65% o'clock, and barrier can sharply descend, so have only the production of the combination process of employing could guarantee the barrier property that it is good.Adhesives on the market only can with resin compounded such as PP, PE, PA, because above resin properties intensity is general, and strength under shock is big, and only suitable heat-sealing film and general pallet, the packing of hollow series products are not suitable for the requirement of strength height and are easy to the packing of product die-cut and printing.For the product (as milk, jam) of some online moulding, can, because its filling speed is fast, outward appearance, edge are cut edge attractive in appearance, then can't use this material.
Summary of the invention
The purpose of this utility model provides a kind of food, drug packaging sheet material with high obstructing performance, environment-protecting asepsis.It has high barrier, and effectively gas such as blocking oxygen passes through; Fuel resistance, organic solvent resistance are good, are applicable to the packing of oils, organic solvent etc.; And have fragrance protectiveness, can keep the fragrance of content, intercept of the influence of extraneous smell it; Can also all kinds of pallets of Heat forming, cup series products, barrier property does not produce any influence.
Technical solution of the present utility model is that food, drug packaging comprise barrier layer with sheet material, on the two sides of barrier layer, be provided with bonding coat, on bonding coat, be provided with upper and lower base membrane layer, base membrane layer is a polystyrene layer, barrier layer is ethylene-vinyl alcohol or evoh layer, and described bonding coat is the maleic anhydride graft copolymer layer.
The thickness of ethylene-vinyl alcohol of the present utility model or ethylene-vinyl alcohol copolymer barrier layer can be 0.01-0.5mm, and the thickness of maleic anhydride graft copolymer bonding coat can be 0.005-0.5mm.
Principle of the present utility model is that food, drug packaging are impact resistant polystyrene HIPS with the base membrane layer of sheet material, and HIPS is the thermoplastic environment-protecting plastics, and odorless, tasteless is nontoxic, grease resistance and chemistry are strong, impact strength is good, and impact strength is also good under the low temperature, is easy to printing.Bonding coat adopts maleic anhydride graft copolymer, a kind of improved polyalkene of forming by modified poly ethylene and modified polypropene, owing on polyolefin chain, introduced adhesive bonding property functional group, the adhesive bonding property that has extra-heavy when making it with air block resin bonds such as EVOH, and can in long-time, keep effect, have remarkable bonding persistence and food hygiene.Handle adhesive bonding property and the food hygiene that still keeps excellence through overaging hot water and boiling, can relievedly use as packaging material for food.High-obstruction adopts ethylene-vinyl alcohol or ethylene-vinyl alcohol copolymer (EVOH) resin, and EVOH belongs to crystalline resin, and the remarkable barrier and the poly heat that have had both polyvinyl alcohol are melted moulding processability.Passing through of gases such as the effective blocking oxygen of its high obstructing performance, can prolong the fresh-keeping and shelf-life of content, has fragrance protectiveness, the fragrance that can well keep content, intercept the influence of extraneous smell to it, its oil resistant, solvent resistance are good, are applicable to the packing of food such as oils, organic solvent and medicament, it has remarkable extrusion molding in addition, is fit to various films, sheet material, pipe co-extrusion moulding.
The utility model has the advantages that; owing to be provided with the EVOH barrier layer; co-extrusion sheet material through adhesives and HIPS formation high-impact; improved the obstructing capacity of packing greatly to gases such as oxygen; the protection that provides to content has been provided, prolonged shelf-life or subject word that food etc. is subject to the content of oxygen influence.Also improved simultaneously obstructing capacity to water, bacterium and other external substances.Be applicable to the guaranteeing the quality of various suitable product such as food, medicine, other emulsus fluids and liquid, fresh-keeping, protect fragrant and resistance oxygen, water proof packing.In addition, the production technology of this material is also simpler, and manufacturing procedure is few, and environmental pollution is little, and barrier property is good, and environmentally-friendly sanitary is easy to reclaiming, has broad application prospects at the automatic forming packaging field.
