Abstract
A kind of antifog food fresh keeping membrane, belongs to food preservative technology field.The antifog food fresh keeping membrane of the present invention by following weight portion material composition：Tributyl 2-acetylcitrate 20-35 parts, zinc stearate 1-2 parts, hard fatty acids 3-4 parts, newborn A2-5 parts, LLDPE 42-55 parts, metallocene linear-low density polyethylene 30-50 parts, tackifier 0.2-5 parts of lark.The present invention is from the newborn lark A with low temperature active as surfactant so that surface equally has preferable hydrophily to preservative film at low ambient temperatures, and fog can form uniform moisture film in film surface such that it is able to increase the translucency under preservative film low temperature.Main component of the present invention is PE, it is to avoid use PVC, safety and reliability.
Description
Technical field
The present invention relates to a kind of antifog food fresh keeping membrane, belong to food preservative technology field.
Background technology
Preservative film is a kind of plastic packing product, generally it is made up of polymerisation with ethene of masterbatch, it is mainly used in the occasions such as microwave food heating, refrigerator food are preserved, fresh and prepared food is packed, is all widely used in family life, supermarket sales field, hotel and industrial food packaging applications.Different according to material therefor and addition plasticiser, preservative film is divided into polytype, is applicable to different occasions.Preservative film receives the favor of people with it the characteristics of convenient, economical, attractive in appearance.However, due to generally with the addition of plasticiser in process of production, influence of the preservative film to health also receives the concern of people.
Most preservative films that in the market is sold all are with ethene masterbatch as raw material are made as conventional polybag.Some preservative film materials are polyethylene (abbreviation PE), this material not plasticizer-containing, are used more comparatively safe；Some materials are polyvinyl chloride (abbreviation PVC), and this material is frequently added the raw materials such as stabilizer, lubricant, secondary process agent, there is certain harm to human body.
The content of the invention
It is an object of the invention to provide a kind of antifog food fresh keeping membrane.
Technical scheme includes as follows：
The antifog food fresh keeping membrane of the present invention by following weight portion material composition：Tributyl 2-acetylcitrate 20-35 parts, zinc stearate 1-2 parts, hard fatty acids 3-4 parts, newborn A2-5 parts, LLDPE 42-55 parts, metallocene linear-low density polyethylene 30-50 parts, tackifier 0.2-5 parts of lark.
The beneficial effects of the invention are as follows：
The present invention is from the newborn lark A with low temperature active as surfactant so that surface equally has preferable hydrophily to preservative film at low ambient temperatures, and fog can form uniform moisture film in film surface such that it is able to increase the translucency under preservative film low temperature.Main component of the present invention is PE, it is to avoid use PVC, safety and reliability.
Specific embodiment
Describe specific embodiment of the invention in detail below in conjunction with technical scheme.
Embodiment 1
35 parts of tributyl 2-acetylcitrate, 2 parts of zinc stearate, 4 parts of hard fatty acids, newborn A5 parts of lark, 55 parts of LLDPE, 50 parts of metallocene linear-low density polyethylene, 5 parts of tackifier.
Embodiment 2
20 parts of tributyl 2-acetylcitrate, 1 part of zinc stearate, 3 parts of hard fatty acids, newborn A2 parts of lark, 42 parts of LLDPE, 30 parts of metallocene linear-low density polyethylene, 0.2 part of tackifier.
Embodiment 3
