Description

A kind of preparation method of SEBS nanometer saddle zip preservative film bag

Technical field

The invention belongs to the Food Packaging technology field, relate in particular to a kind of preparation method of SEBS nanometer saddle zip preservative film bag.

Background technology

The packing of food, preservation, fresh-keeping generally be that to listen materials such as jar, glass, plastic film bag be main with traditional, particularly the food in bulk packing mostly is to adopt flat mouthful or the simple and easy plastic film bag that seals certainly; Closure is relatively poor, easy to be contacted with air; Do not reach fresh-keeping effect, and taint of odour phenomenon and moisture evaporation are serious, lack preservative film bag with high-tech content; Improve the preservation quality of food, prolong fresh keeping time.

Summary of the invention

The invention provides a kind of preparation method of SEBS nanometer saddle zip preservative film bag, solved the freshness protection package preservation agent in the background technology and be prone to cause the pollution to food, the shortcoming of fresh-keeping effect difference.

Technical scheme of the present invention is achieved in that a kind of preparation method of SEBS nanometer saddle zip preservative film bag, comprises following technology:

(1), makes nanometer colloid silver particle: the miniature silver-colored particle of 1.0-1.5% is dissolved in the liquid vehicle; Miniature silver-colored particulate diameter is at the 0.04-0.0001 micron; Liquid vehicle is the aqueous ethanolic solution of pure water or 1.0-2.0%; Under the effect of 50V alternating-current, miniature silver-colored particle keeps suspended state, and is subsequent use;

(2) prepare following material: 100 parts of SEBS resins, rubber filling oil 75-125 part, Vestolen PP 7052 40-115 part, lubricant 0.4-0.8 part, protective agent 0.4-0.6 part, nanometer colloid silver particle 0.5-1.0 part are subsequent use;

(3), the SEBS resin is fully absorbed rubber filling oil, even in stirrer for mixing together with Vestolen PP 7052, lubricant, protective agent and nanometer colloid silver particle again, use the twin screw extruder granulation;

(4), extrude extrusion moulding nanometer saddle-shape preservative film bag in the inflation film manufacturing machine at the plastics of special use, again through assembling tapered end, punch press arrangement, formation SEBS nanometer saddle zip preservative film bag.

The invention has the beneficial effects as follows: with the environmental protection type SEBS nanometer saddle zip preservative film bag of the present invention's making; Have following special benefits: 1, fresh-keeping function: it can avoid contacting of food and oxygen, water vapour and bacterium class; Harmful mushroom that can suppress effectively and kill in the former food simultaneously plays good freshening effect, prolongs the shelf time of food.2, excellent repeatedly opening, enclosing function after the splendid attire food, can use what, and what are got, and breaks a seal repeatedly, make food be in always with isolate from outer air in, leave non-volatile moisture, not taint of odour in the refrigerator in.3, the function easy to use of excellence:, can keep good hygienic state again because its unique saddle-shape shape in the time of can on market, using, had both made things convenient for splendid attire food.4, the preparation of environment-friendly type nano saddle zip freshness protection package, production and simple to operate, the relative cost of preparation is lower, and environmentally safe, can realize large-scale pollution-free industryization like this.

Embodiment

Further describe in the face of preparation method of the present invention down:
