Abstract

The invention discloses a preparation method of a food package material. The method is characterized by comprising the following steps: pouring 100 parts by weight of a polyamide resin, 20 parts by weight of low density polyethylene resin, 6 parts by weight of sorbic acid and 0.5 part by weight of vinyl acetate in a blown film extrusion machine, and stretching the materials at 170-210 DEG C at a rotation speed of 70 r/min for 30 s, so as to form the packaging material. The preparation method provided by the invention employs polyamide resin and low-density polyethylene resin as the main raw materials, which are added with sorbic acid as an antimicrobial agent, so as to play the effects of killing microorganisms. At the same time, the antibacterial substances have volatility and can extend the shelf life of food.

Description

A kind of preparation method of packaging material for food
Technical field
The present invention relates to food and keep technical field, specifically a kind of preparation method of packaging material for food.
Background technology
Packaging material for food, for food is provided protection, prevents that food is subject to the pollution of external microbe or other materials, prevents or reduces oxidation have irreplaceable effect with other reaction aspects, is the important means of food preservation.
Polyamide resin is tough and tensile, the transparency is good, has good gloss, and tensile strength, tensile strength are higher, also have good thermotolerance, winter hardiness, oil-proofness and organic solvent, wear resistance.Paracentesis resistance is good, and soft, antifungal, and oxygen barrier is good, but poor to the barrier of water vapour.
Low Density Polyethylene, English name: Linar Low Density Polyethylene, be called for short LLDPE, that ethene and a small amount of high alpha-olefin are under catalyst action, a kind of multipolymer forming through high pressure or low-pressure polymerization, LLDPE is nontoxic, tasteless, odorless, the particle that is creamy white, and has good heat-resisting, cold-resistant, resisting environmental stress and cracking, the performances such as tear-resistant intensity, and can acid-and base-resisting, organic solvent properties.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of packaging material for food.
Object of the present invention can be achieved through the following technical solutions:
A kind of preparation method of packaging material for food, it is characterized in that, comprise the following steps: 100 weight parts of polyamide resins, 20 weight part ldpe resins, 6 weight part Sorbic Acids, 0.5 weight part softening agent are poured into and extruded in inflation film manufacturing machine, at 170-210 ℃, rotating speed 70r/min, residence time 30s, stretches and forms wrapping material of the present invention.
Described softening agent is vinyl acetate.
Beneficial effect of the present invention: it is main raw material that preparation method of the present invention be take polyamide resin and ldpe resin, and adding Sorbic Acid is antiseptic-germicide, has the effect of killing microorganisms.Antimicrobial substance has certain volatility simultaneously, can extend the quality guaranteed period of food.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.
Embodiment 1
A kind of preparation method of packaging material for food, it is characterized in that, comprise the following steps: 100 weight parts of polyamide resins, 20 weight part ldpe resins, 6 weight part Sorbic Acids, 0.5 weight part vinyl acetate are poured into and extruded in inflation film manufacturing machine, at 170-210 ℃, rotating speed 70r/min, residence time 30s, stretches and forms wrapping material of the present invention.
