Description
Technical field
The present invention relates to a kind of transparent membrane, particularly relate to a kind of obstruct ultraviolet line style transparent membrane.
Background technology
Transparent film packaging, can it can be clearly seen that the commodity in packaging with people under illumination, the color of its bright-coloured beauty, exquisite eye-catching outward appearance etc. are very clear, and contributing to consumer understands the concrete condition of commodity, improves the desire to purchase of consumer.But high transparency packaging exists the biggest defect, it is simply that under the effect of light, commodity generation chemical reaction can be made, accelerate the rotten of commodity.Especially in the commodity of medicine, food etc, show particularly evident.Light initiated oxidation reflects, adds the decomposition of instant food Middle nutrition composition, promotes food apoilage.On protection commodity and displaying commodity problem; bring awkward circumstances: in order to ensure commodity in storing and sales process; quality will not produce significantly decline; in the case of a lot; have to sacrifice the transparency packed; thin film is made the opaque product staying agent containing shadings such as white carbon blacks, or compound by its opaque substrate layer with paper, aluminium foil etc, make opaque opacity laminated film.Though solving commodity lucifuge to guarantee the quality problem, but sacrificing the transparency of packaging, being that the one of packing film is the most sorry all the time.
Summary of the invention
It is an object of the invention to solve problem present in current techniques, it is provided that a kind of obstruct ultraviolet line style transparent membrane.
For reaching above-mentioned purpose, the technology used in the present invention means are: a kind of obstruct ultraviolet line style transparent membrane, by extruding, inflation film manufacturing machine is three-layer co-extruded to be formed, having outer layer, middle level and an internal layer being combined with each other, wherein internal layer uses linear low density polyethylene (LLDPE) to be substrate and metallocene Low Density Polyethylene, opening agent mix according to the ratio of 4. 5～5.5:4～5:0.4～0.6；Described middle level uses linear low density polyethylene (LLDPE) and Low Density Polyethylene to mix according to the ratio of 5.5～6.5:3.5～4.5；Described cladding material uses linear low density polyethylene (LLDPE), Low Density Polyethylene, UV absorbent, antioxidant to mix according to the ratio of 4.5～5.5:3.5～4.5:0.4～0.6:0.4～0.6；In extruded velocity: in: outer speed is: 30%:40%:30%.
Further, described linear low density polyethylene (LLDPE) uses inflation film level special line-type ldpe resin FD21H, and described Low Density Polyethylene uses LD617 resin, and described metallocene Low Density Polyethylene uses 2045G resin.
Further, described UV absorbent is to use chlorination benzotriazole UV absorbers, and described antioxidant uses food grade antioxidants BHT.
Further, described UV absorbent is UVP-327.
The beneficial effects of the present invention is: outer layer adds UV absorbent; can absorbing polymeric is sensitive consumingly ultraviolet light; and can be that harmless form of thermal energy is released by energy conversion; maximum absorption wavelength scope is 280～390nm; thus intercept the food in UV contact packaging, the taste of food, color and nutritional labeling in packaging are played more preferable protected effect；Outer layer adds food grade antioxidants BHT, both safety and environmental protection, can delay or suppress again the oxidizing process of plastic sheeting to carry out, thus stop the aging of thin film and extend its service life, also can play synergism with UV absorbent simultaneously, more effectively absorb the ultraviolet to food harm, intercept ultraviolet to the harm of food in packaging, the shelf-life of raising food；UV absorbent and antioxidant are all added on the outer layer of thin film, it is to avoid with Food Contact, prevent the pollution to food, more environmental safety；Internal layer additive opening agent, can effectively prevent film blocking, and made finished product has more preferable opening performance；Internal layer uses metallocene Low Density Polyethylene, thin film is made to have good heat sealability, can be made into the packaging bag that various heat sealability is excellent, have good antipollution heat sealability simultaneously, solution packing liquid, powder body based food seal bad problem when sealing；Outward, in, interior three layers all use linear low density polyethylene (LLDPE) and consumptions more than 50%, because linear low density polyethylene (LLDPE) has the advantages such as intensity is big, good toughness, rigidity are big, heat-resisting, tolerance to cold is good, also there is good environmental stress crack resistance, the performance such as impact strength, tear-resistant intensity, made thin film more can shock resistance, possess the advantage of heavy duty packaging film, can use under various circumstances simultaneously, still keep good performance；The material that production process is used is all the plastics that the transparency is splendid, and blown thin film has the preferable transparency, meets client's requirement to product high transparency.
Detailed description of the invention
