Abstract
The present invention discloses a high-isolation full-degradation non-toxic spray aluminized nanometer film and the application thereof, which belongs to a packing material. The present invention is especially used for packing foods and medicines. The present invention is characterized in that the material comprises 30 to 50% of plasticity starch, 45 to 68% of degradable polycaprolactone, 1 to 5% of low-molecular polyhexenol wax, and 0.3 to 2% of degradable color agglomerate. The materials are mixed, extruded and manufactured into agglomerate according to the proportion, the agglomerate is extruded, stretched and processed into a thin film with the thickness of 15 to 25 mu m, one layer of ultra-fine silicon oil with the thickness of 5 to 10 mu m is coated on the film, and the surface of the thin film which is coated with the ultra-fine silicon oil is sprayed and plated with an aluminum layer. The thin film is mainly applied to the soft package of foods and medicines. The thin film with the nanometer aluminum layer has high partition property, the air permeability is 10 times as little as the air permeability of the common plastic thin film, and thereby, the foods and the medicines can be stored for a long time and can not be deteriorated. The thin film is made of full-degradation compatible materials, can be degraded and burned, and is easy to recycle. Because the material is directly contacted with the foods and the medicines through aluminum, the pollution of harmful substances generated in the process of storing and transporting of plastic products is avoided. The present invention is a new comparatively ideal packing material for packing foods and medicines.
Description
Technical field
High-isolation full-degradable non-toxic spray aluminized nano-film that the present invention relates to and uses thereof belongs to packaging material, is high-barrier, the high-fall flexible packing material of separating and increasing the holding time specifically, is particularly useful for the flexible package of food and medicine.
Background technology
At present, the flexible packing material of food and medicine mainly is the combination product of plastic products and a spot of plastic sheeting and aluminium foil, these films all be do not degrade, difficult reclaim, the material of difficult to burn, these materials to the severe contamination of environment by universally acknowledged; Because of causing the shelf-life of food and medicine to shorten to manufacturing enterprise, packaging material bring serious loss; Medical circle is found, plastics itself can discharge pernicious gas, and because of accumulating in the enclosed package bag midium or long term, concentration also increases along with the prolongation of sealing time, cause food and medicine etc. to be subjected in various degree pollution, to the mankind particularly to children's health with grow and bring very big influence; Plastics directly contact for a long time with food, medicine, also can produce harmful substance, contaminated food products and medicine with itself and auxiliary material thereof, auxiliary agent; A kind of research of high-isolation full-degradable non-toxic spray aluminized nano-film and use imperative.
Summary of the invention
Purpose of the present invention is intended to improve the deficiency of prior art, a kind of increase food and medicine soft packaging material barrier property are provided, prolong the storage life of food and medicine, reduce and pollute, make food and medicine soft packaging material and environmentally compatible, environmental protection is compatible, avoids the aluminium-plated film of nanometer and uses thereof of a kind of high-isolation full-degradable nonhazardous of the pernicious gas that plastics self discharge.
In order to achieve the above object, the present invention is achieved in that it comprises (by weight percentage):
A, plasticity starch 30-50%;
B, degradable poly caprolactone 45-68%;
C, low-molecular-weight polyhexene wax 1-5%;
D, degradable Masterbatch 0.3-2%;
E, with above-mentioned material blend in proportion, extrude, make master batch;
F, with above-mentioned master batch is extruded, stretch process becomes 15-25 μ m film;
G, with the ultra-fine silicone oil of film coated one deck 5-10 μ m;
H, will be coated with the aluminium lamination of the one side spraying plating 20-40 nanometer thickness of the ultra-fine silicone oil film of one deck.
The optimal seeking of raw and processed materials scheme of high-isolation full-degradable non-toxic spray aluminized nano-film of the present invention comprises plasticity starch 35-45%, degradable poly caprolactone 50-63%, low-molecular-weight polyhexene wax 1.3-4%, degradable Masterbatch 0.7-1.6% by weight percentage.
The raw material preferred plan of high-isolation full-degradable non-toxic spray aluminized nano-film of the present invention comprises plasticity starch 40%, degradable poly caprolactone 56%, low-molecular-weight polyhexene wax 3%, degradable Masterbatch 1% by weight percentage.
In order to achieve the above object, high-isolation full-degradable non-toxic spray aluminized nano-film of the present invention is applied in the flexible package of food, medicine.
The film that the present invention has the nanometer aluminium lamination has very high interrupting performance, its air penetrability is than low 10 times of general plastic sheeting, thereby can guarantee that food and medicine long preservation never degenerate, this film is the high-fall environmentally compatible material of separating, degradable, incendivity, reclaim easily, because this material and food, what medicine etc. directly contacted is aluminium, thereby avoided plastic products in storage and transport process, particularly the harmful substance that produces in long-term directly contact process with food and medicine etc. is to the pollution of food and medicine, avoided its harm to health of people, the present invention is a kind of more satisfactory attached with environment protection requirement, the food compatible with environmental protection, the medicine new packaging materials.
