The film comprises a film body formed by an intermediate layer, first and second surface layers, wherein the intermediate layer is composed of 65%-87% of MLLDPE1018HA and 13%-35% of a first functional master batch, the first or second surface layer is composed of 65%-87% of MLLDPE1018HA and 13%-35% of a second functional master batch. The film special for grass silage is produced by a three-layer co-extrusion film blowing production process and has advantages of high tensile strength, good puncture resistance, good UV resistance strength, barrier properties, good plasticity, ageing resistance, safety, environment protection, opacity, thin film and uniform thickness, and fully satisfies operation requirements of market for various indexes of the film.
Description
Technical field
The present invention relates to plastic film packaging field, be specifically related to a kind of grass silage dedicated film.
Background technology
Grass silage is the fermentation of utilizing microorganism, and simple, the economic and reliable method of one of preserving for a long time green forage nutrition, is to ensure the domestic animal effective measures of stable market supply roughage all the year round.Just there is the record of alfalfa ensilage fermentation process in China in the books such as Yuan Dynasty's " Wang Zhennong book ", and ensiling has become an important technology in animal husbandry now.
Grass silage has many good qualities: not only can preserve by the mode of modulation hay, also can preserve by the mode of ensiling; Can reduce the loss of nutriment, if silage facilities advanced person, technical operation is suitable, and the loss of nutrition is generally no more than 15%, and keeps more than 90% carrotene in green grass; Ensilage can improve palatability and the digestibility of domestic animal, ensiling herbage after microorganism fermentation has sour fragrance, soft and succulency, good palatability, can stimulate the appetite of domestic animal, lactic acid obviously improves digestibility to the spread effect of stomach in addition, and ensiling can make herbage remain on for a long time blue or green fresh state, be rich in protein, multivitamin and mineral matter, the feed of high nutritive value can be provided for domestic animal all the year round; The manufacturing process of ensiling is the restriction of climate condition not, and overcast and rainy season or bad weather, while being difficult to modulate hay, are made ensiling impact less.
The key of grass silage process is to keep anaerobic environment, if there is Air infitration, saccharomycete and mould will breed, not only consume sugar and lactic acid in ensiling herbage, and decomposition of cellulose and other cell wall constituents, produce harmful metabolite, cause that temperature and pH value rise, and make the dry of ensiling herbage and nutrient all be subject to very large loss.The light transmittance of membrane material also affects the effect of grass silage, and transmitted light can promote the loss of some nutriment, is failed with transparent plastic sheeting as Grass Silage Films.。Therefore, for the plastic sheeting of grass silage, the effect of grass silage is played to very important effect.But the grass silage film of selling in the market exists that hot strength is not high, paracentesis resistance is poor, thickness and uneven thickness, tack are bad, cause that broken rate is very high, sealing is poor, light transmittance is strong, can not effectively keep the shortcomings such as anaerobic environment.
Summary of the invention
For overcoming the deficiency of above-mentioned technical problem, the invention provides the thin and even thickness of a kind of high tensile, high paracentesis resistance, strong sealing, film, shrinkage is good, light transmission is poor grass silage dedicated film.
Technical problem solved by the invention can adopt following technical scheme to realize:
A kind of grass silage dedicated film, comprise a film body, by an intermediate layer and first, the second top layer composition, it is characterized in that: described intermediate layer is made up of 65～87% MLLDPE1018HA and the first functional masterbatch of 13～35%, the each component of described the first functional masterbatch and mass percent are: white master batch 2～8%, LLDPE54008～15%, PIB tackify master batch 2～7%, anti-aging master batch 1～5%, described first, the second top layer is evenly made up of 65～87% MLLDPE1018HA and the second functional masterbatch of 13～35%, the each component of described the second functional masterbatch and mass percent are: POE30202.4～3.0%, grass green master batch 1.0～1.8%, white master batch 0.6～1.2%, LLDPE54005～15%, PIB tackify master batch 3～9%, anti-aging master batch 1～5%.
Preferably, the mass percent in described intermediate layer is 35～45%, and the mass percent on described the first top layer is that the mass percent on the 25～35%, second top layer is for being 20～40%.
