Abstract
The invention discloses an ultraviolet ray-blocking transparent film. The ultraviolet ray-blocking transparent film is formed by an extrusion film blowing machine in a manner of three-layer co-extrusion, and comprises an outer layer, a middle layer and an inner layer which are compounded together, wherein the inner layer uses linear low density polyethylene as a substrate and uses metallocene low density polyethylene and an antiblocking agent; the middle layer uses linear low density polyethylene and low density polyethylene; the outer layer uses linear low density polyethylene, low density polyethylene, an ultraviolet ray absorber and an antioxidant; the ratio of the extrusion speeds of the inner layer, the middle layer and the outer layer is 30%:40%:30%. The film disclosed by the invention is good in good mechanical strength and blocking property, can be used for the commodity packaging materials of medicines, foods and the like, and is capable of effectively solving the problem of commodity light-resistant quality guaranteeing, so that commodities are capable of keeping beauty and ensuring no declining of quality during storage and sales processes. The film is a practical and functional film.
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, people can clearly see commodity in packaging under illumination, the color of its bright-coloured beauty, exquisite eye-catching outward appearance etc. are very clear, contribute to the concrete condition that consumer understands commodity, improve the desire to purchase of consumer.But high transparency packaging exists very large defect, is exactly under the effect of light, can makes commodity generation chemical reaction, accelerate the rotten of commodity.Especially, in the commodity of medicine, food and so on, show particularly evident.Light initiated oxidation reflects, adds the decomposition of instant food Middle nutrition composition, promotes food apoilage.On protection commodity and displaying merchandise problem; bring awkward circumstances: in order to ensure commodity in storing and sales process; the unlikely generation of quality significantly declines; in a lot of situation; have to sacrifice the transparency of packing; film is made and stays the opaque product of agent containing shadings such as carbon blacks, or by the compound of the opaque substrate layer of it and paper, aluminium foil and so on, make opaque opacity laminated film.Though solve commodity lucifuge to guarantee the quality problem, sacrifice the transparency of packaging, be that of packing film is sorry greatly all the time.
Summary of the invention
The object of the invention is to solve Problems existing in current techniques, provide a kind of and intercept ultraviolet line style transparent membrane.
For achieving the above object, 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, have be combined with each other skin, middle level and internal layer, wherein internal layer adopts linear low density polyethylene (LLDPE) to be that substrate and metallocene low density polyethylene (LDPE), opening agent mix according to the ratio of 4. 5 ~ 5.5:4 ~ 5:0.4 ~ 0.6; Described middle level adopts linear low density polyethylene (LLDPE) and low density polyethylene (LDPE) to mix according to the ratio of 5.5 ~ 6.5:3.5 ~ 4.5; Described cladding material adopts linear low density polyethylene (LLDPE), low density polyethylene (LDPE), ultra-violet absorber, 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) adopts inflation film level special line-type ldpe resin FD21H, and described low density polyethylene (LDPE) adopts LD617 resin, and described metallocene low density polyethylene (LDPE) adopts 2045G resin.
Further, described ultra-violet absorber adopts chlorination benzotriazole UV absorbers, and described antioxidant adopts food grade antioxidants BHT.
Further, described ultra-violet absorber is UVP-327.
Beneficial effect of the present invention is: outer interpolation ultra-violet absorber, can the ultraviolet light of absorbing polymeric sensitivity consumingly, and can be that harmless form of thermal energy is released by energy conversion, maximum absorption wavelength scope is 280 ~ 390nm, thus the food intercepted in UV contact packaging, better protected effect is played to the taste of food, color and nutritional labeling in packaging; Outer interpolation 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 film and extend its service life, also can play synergy with ultra-violet absorber simultaneously, more effectively absorb the ultraviolet to food harm, intercept the harm of ultraviolet to food in packaging, improve the shelf-life of food; Ultra-violet absorber and antioxidant are all added on the skin of film, avoid and Food Contact, prevent from, to the pollution of food, having more environmental safety; Internal layer additive opening agent, effectively can prevent film blocking, and made finished product has better opening performance; Internal layer uses metallocene low density polyethylene (LDPE), film is made to have good heat sealability, can be made into the packaging bag that various heat sealability is excellent, there is good antipollution heat sealability simultaneously, solve packing liquid, powder based food seals bad problem when sealing; Outward, in, interior three layers all use linear low density polyethylene (LLDPE) and consumption more than 50%, because linear low density polyethylene (LLDPE) has the advantages such as intensity is large, good toughness, rigidity are large, heat-resisting, cold resistance is good, also there is good environmental stress crack resistance, the performance such as impact strength, tear-resistant intensity, made 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 uses is all transparent splendid plastics, and blown film has the good transparency, meets the requirement of client to product high transparency.
Detailed description of the invention
embodiment 1
A kind of obstruct ultraviolet line style transparent membrane, by extruding, inflation film manufacturing machine is three-layer co-extruded to be formed, have be combined with each other skin, middle level and internal layer, wherein internal layer adopts linear low density polyethylene (LLDPE) to be that substrate and metallocene low density polyethylene (LDPE), opening agent mix according to the ratio of 4. 5 ~ 5.5:4 ~ 5:0.4 ~ 0.6; Described middle level adopts linear low density polyethylene (LLDPE) and low density polyethylene (LDPE) to mix according to the ratio of 5.5 ~ 6.5:3.5 ~ 4.5; Described cladding material adopts linear low density polyethylene (LLDPE), low density polyethylene (LDPE), ultra-violet absorber, 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%.
