Abstract
The invention discloses a packing bag for preventing mold of grain. The thin film of the packing bag comprises the following ingredients in parts by weight: 100 parts of polyvinyl chloride resin, 15-25 parts of polypropylene resin, 24-26 parts of dioctyl phthalate, 14-18 parts of dioctyl sebacate, 6-8 parts of nano silicon dioxide, 2-4 parts of nano titanium oxide, 4-6 parts of light calcium carbonate, 4-6 parts of activated carbon, 3-5 parts of octadecyl ammonium chloride, 4-6 parts of a calcium-zinc composite stabilizer, 2-4 parts of stearic acid, and 1.5-2.5 parts of liquid paraffin.
Description
Technical field
The present invention relates to field of packaging material, relate in particular to a kind of grain mold proof packing bag.
Background technology
Freshness protection package is the plastic packing product of the class fresh-keeping foodstuff commonly used of people, has now a lot of families all to be unable to do without them.Food in microwave oven heating can be used, and in refrigerator, storing food can be used equally, and it is mainly in order to prevent the erosion to food of dust and bacterium that people use freshness protection package.
Most freshness protection packages of selling are in the market the same with conventional plastics bag, all take ethene masterbatch as starting material, according to the different sorts of ethene masterbatch, freshness protection package can be divided into three major types: the first is polyethylene, be called for short PE, this material is mainly used in the packing of food, the fruit usually buying, this film that vegetables are used, be included in supermarket purchase the work in-process of returning all use be this material;
The second is polyvinyl chloride, is called for short PVC, and this material also can be for food product pack, but it has a certain impact to the security of human body; The third is polyvinylidene dichloride, is called for short PVDC, is mainly used in the packing of the products such as some prepared food, ham.In these three kinds of freshness protection packages, the freshness protection package of PE and this bi-material of PVDC is safe to human body, can relievedly use, and PVC freshness protection package contains carcinogenic substance, larger to harm.From physical angle, freshness protection package has appropriate oxygen-permeable and Water Vapour Permeability, regulates by fresh-keeping product oxygen recipe ingredient and moisture recipe ingredient around, intercepts koniology, thereby extends the freshness date of food.
Grain is the necessary food that China resident depends on for existence, but make grain loss serious because going mouldy every year, and traditional anti-method great majority that go mouldy are to utilize spontaneous controlled-atmosphere (MA) packing, be the interior humidity of permeability adjustment packing, the gas that utilizes grain self respiratory metabolism and plastics film, thereby extend grain storage freshness date.But this method of preventing and treating is single, and anti-mold effect is not remarkable, therefore, explore a kind of novel food product mouldproof packaging, bag of research and development crucial especially.
Summary of the invention
The object of the invention is to propose a kind of grain mold proof packing bag, by the adjustment to packing bag component, overcome the defect of prior art, make packing bag there is antimildew function, guarantee the fresh-keeping effect of grain.
For reaching this object, the present invention by the following technical solutions:
A kind of grain mold proof packing bag, this film is made up of following component in weight part: 100 parts of polyvinyl chloride (PVC) RESINS, acrylic resin 15-25 part, dioctyl phthalate (DOP) 24-26 part, dioctyl sebacate 14-18 part, nano silicon oxide 6-8 part, nano-titanium oxide 2-4 part, light calcium carbonate 4-6 part, gac 4-6 part, octadecyl ammonium chloride 3-5 part, calcium-zinc composite stabilizing agent 4-6 part, stearic acid 2-4 part, whiteruss 1.5-2.5 part.
Preferably, this film is made up of following component in weight part: 100 parts of polyvinyl chloride (PVC) RESINS, 20 parts of acrylic resins, 25 parts of dioctyl phthalate (DOP)s, 16 parts of dioctyl sebacates, 7 parts of nano silicon oxides, 3 parts of nano-titanium oxides, 5 parts of light calcium carbonates, 5 parts of gacs, 4 parts of octadecyl ammonium chloride, 5 parts of calcium-zinc composite stabilizing agents, 3 parts of stearic acid, 2 parts of whiterusss.
Beneficial effect of the present invention is:
The present invention is using nano silicon oxide, nano-titanium oxide, light calcium carbonate, activated carbon combined as antibacterial and mouldproof composition, can moisture absorption protection against the tide antifog, not dewfall, thus grain is not gone mouldy, long-period freshness preserving.
