Abstract
A fresh keeping film is prepared from, by weight, 3 parts to 4.5 parts of mannan, 0.1 part to 0.15 part of liquid paraffin, 10 parts to 25 parts of polyethylene, 4 parts to 6 parts of nanoscale Al2O3 powder, 5 parts to 10 parts of ethylene glycol distearate, 4 parts to 8 parts of vinyl siloxane, 2 parts to 7 parts of methylcellulose, 0.5 part to 0.8 part of potassium hydroxide, 1 part to 3.5 parts of rose essential oil, 3 parts to 4.5 parts of soda, 4 parts to 12 parts of alginate, 3 parts to 7 parts of nano-zinc oxide, 5 parts to 8 parts of potassium carbonate, 5 parts to 7 parts of urea-formaldehyde resin and 4 parts to 8 parts of neutral oil. The fresh keeping film has the advantages of being high in wear resistance, antibacterial property and strength, easy to store, capable of decreasing the water loss rate of freshness-retained objects, long in conservation time and free of toxin.
Description
Technical field
The present invention relates to a kind of preservative film.
Background technology
The annual food abandoning eating because of corrupt exceedes the food summation of relief disadvantaged country of United Nations in the world at present.For extending the maintenance phase of food high freshness, preventing the putrid and deteriorated of food to greatest extent, needing to use preservative film to solve this problem.The occasions such as preservative film can be used for microwave food heating, refrigerator food is preserved, fresh and prepared food packaging, are all widely used at family life, sales field, supermarket, hotel and industrial food packaging applications.Preservative film is convenient with it, economical, feature attractive in appearance receives the favor of people.But owing to generally with the addition of fluidizer in process of production, preservative film also receives the concern of people to the impact of HUMAN HEALTH.But traditional preservative film lacks germ resistance, security is not good, need improve further, work out antibacterial preservative film, antibacterial preservative film can kill or suppress food in processing, accumulating and treating processes, retain in the microorganism on surface, extends shelf-lives and the security of food.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of preservative film, tool has good wearability, germ resistance, and intensity is high, easily preserves, and fresh-keeping article can be made to lower percentage of water loss, and the shelf time is of a specified duration, and nontoxic.
For solving prior art problem, technical scheme provided by the invention is, a kind of preservative film, and it is made up of the raw material of following parts by weight:
Mannosans 3-4.5 part, whiteruss 0.1-0.15 part, polyethylene 10-25 part, nano level Al2O3 powder 4-6 part, Ethylene Glycol Distearate 5-10 part, vinylsiloxane 4-8 part, methylcellulose gum 2-7 part, Pian Zhuan caustic potash flakes 0.5-0.8 part, Flos Rosae Rugosae quintessence oil 1-3.5 part, soda 3-4.5 part, alginates 4-12 part, nano zine oxide 3-7 part, salt of wormwood 5-8 part, urea-formaldehyde resin 5-7 part, neutral oil 4-8 part.
The invention has the beneficial effects as follows: preservative film of the present invention, tool has good wearability, germ resistance, and intensity is high, easily preserves, and fresh-keeping article can be made to lower percentage of water loss, and the shelf time is of a specified duration, and nontoxic.
