Description
Technical field
The utility model relates to a kind of novel paper liquid milk high-isolating packaging film.
Background technology
The UHT liquid milk is UHTS (Ultra High Temperature, UHT) milk.
The main nutrient composition of milk is milk fat, protein, toffee, mineral matter, vitamin etc.Wherein fat, protein (amino acid) and vitamin etc. are easy to by dioxygen oxidation and losing nutritive value and fresh mouthfeel.
Prevent the effective ways of oxidation deterioration, two kinds of approach are arranged.The one, reduce circulation and storage temperature (being generally 0-5 ℃), thereby reduce oxidation rate.Here it is why usually with the reason place of milk keeping in refrigerator.But, on the process of circulation and storage condition, remain 0-5 ℃ low temperature, be not easily, be subjected to the high restriction of appointed condition and economic cost.
The approach of another kind of anti-oxidation adopts the barrier packaging material exactly, cuts off the passage that oxygen enters package interior, and it is oxidized to avoid suckling.
At present, the manner of packing of UHT liquid milk mainly contains two types: the one, and aseptic bag, the Lilezhen of Sweden Lile packaging Co., Ltd; This product structure is PE22//PAPER120/PE+EAA22/AL9/PE50; The 2nd, three layers or five layers black and white plastic foil of coextrusion, this product structure is PE40/TIE8/EVOH8/TIE8/PE40.The former barrier height, the shelf bandwagon effect is good, and shelf life can reach more than 6 months, and good moldability has almost monopolized the high-end market of liquid milk-packing, but packing cost is than higher, and need on the special purpose packaging machine of Tetrapack company, use, exclusiveness is strong.The latter's packing cost is cheap, but toughness of material is bad, walks broken bag rate height in the machine process, and especially obvious under low-temperature condition, shelf life was generally 60 days.If under the environment of summer high-temperature high humidity, shelf life only is 30 days.
Developing a kind of novel product structure between Tetrapack product structure and co-extrusion product structure is we packaging material scientific research personnel's responsibility, when increasing shelf-life, reduction bottom pour ladle rate, reducing cost, promotes the class of product.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, a kind of novel paper liquid milk high-isolating packaging film is provided, it has the top grade of Tetrapack structure, the advantage of high-barrier, possesses the low-cost characteristics of coextruded structure simultaneously, has good market value.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of novel paper liquid milk high-isolating packaging film, described packaging film is 10 layers of structure, outermost layer be common BOPP rete, common BOPP rete lower surface be printed with the ink printing layer, below the BOPP of ink printing rete, be followed successively by paper layer, on accept layer, down accept layer, go up adhesive layer, barrier layer, adhesive layer, inferior hot sealing layer and low-temperature heat-sealing layer down.
Outermost layer of the present utility model is common BOPP rete, be easy to buying on the market, and cost is low, polyacrylic intensity will be higher than polyethylene simultaneously, so can realize the purpose of material attenuate, and polyacrylic printing adaptability is good more than polyethylene, so can promote the yield rate of product to a great extent; Ink lay is common chlorinated polypropylene printing ink, needn't require scratch resistance good, wearability is good, therefore anti-dioxygen water-based is good, has reduced material cost, and mode of printing to be become by the table seal be the lining seal, make that the glossiness of product is good, even on shelf, put for a long time, the friction of experience how many times, printing ink can not come off; Paper layer adopts the single copper paper of 120 grams; On accept layer and need do sided corona treatment so that strengthen combined strength bination with paper layer; Last adhesive layer and following adhesive layer in order to reduce production costs, can be sneaked into 50% linear LDPE; Barrier layer can adopt EVOH to reach the purpose of high-barrier, also can adopt the purpose that intercepts in the MDX6 realization; Inferior hot sealing layer and low-temperature heat-sealing layer guarantee that material has very high heat seal strength and hot sticky intensity.Guarantee on client's bottle placer, to have and well walk the machine performance, play the function of antiultraviolet simultaneously, promoted the shelf-life of product to a certain extent.
The utility model is a kind of novel UHT liquid milk high-isolating packaging film, has proposed a kind of common in the market liquid milk-packing structure that is different from, and has the papery outward appearance, packing class height, barrier property height, the characteristics that cost is low.
Novel paper liquid milk-packing film described in the utility model adopts in the intaglio plate and prints, and is different from surface printing in the market, and therefore the performance requirement to printing ink reduces, and the glossiness of product improves, and sanitation performance improves.
The utility model all has higher barrier to gas, moisture and ultraviolet ray, simultaneously in conjunction with the function of paper, can make shelf-life of product at 4 months;
The utility model adopts paper and the compound structure of high-resistant diaphragm, is different from Tetrapack and relies on AL to realize barriering effect, has deflection preferably, makes that membranous sense of the present utility model is comfortable, high-grade.
The utility model material solvent residual quantity is low, and printed layers avoids ink penetration in content outside barrier layer, has good fragrance protectiveness, has kept the original local flavor of content.
Film described in the utility model has good flexibility (adaptability) of operation, operation is simple, only need 3 procedures just can reach 4 months shelf-life, with through 5 procedures, the Tetrapack structure that reaches 6 months shelf-lifves is compared has very big advantage, and cost of the present utility model only is 1/2 of a Tetrapack infrastructure cost.
