The utility model provides a kind of herbage film, comprise at least one deck A layer composition, at least one deck B layer composition, at least one deck C layer composition by the composition that necessarily puts in order, wherein composition put in order as BACAB puts in order, wherein the ratio of the thickness of each layer is followed successively by 1:1:2:1:1;
Or for BCACB puts in order, wherein the ratio of each layer thickness is followed successively by 1:2:1:2:1;
Or for ABBBC puts in order, wherein the ratio of each layer thickness is followed successively by 1:1:1:1:2.
Wherein A layer comprises the metallocene linear low density polyethylene 82 ~ 90% by mass component composition, thickening masterbatch 6 ~ 10%, anti-aging mother material 4 ~ 8%;
B layer comprises the metallocene linear low density polyethylene 90 ~ 94% being added with nano imvite by mass component composition, brightens shading masterbatch 6 ~ 10%;
C layer comprises the metallocene linear low density polyethylene 92 ~ 96% by mass component composition, anti-aging mother material 4 ~ 8%.
Wherein the thickening masterbatch of A layer is 60% polybutene and LLDPE carrier compositions, and anti-aging mother material is the composition of light stabilizer, ultraviolet ray adsorbents and LLDPE carrier; Described B layer brightens the composition that shading masterbatch is titanium dioxide and proactively answer to a riddle polyethylene support; Described C layer anti-aging mother material is the composition of light stabilizer, ultra-violet absorber and property low density polyethylene (LDPE) carrier.
The metallocene linear low density polyethylene that wherein B layer is added with nano imvite is prepared from through blending technology by the imvite and metallocene linear-low density polyethylene choosing 600 order-800 order specifications.
The utility model provides a kind of herbage film, comprise at least one deck A layer composition, at least one deck B layer composition, at least one deck C layer composition by the composition that necessarily puts in order, wherein A layer pulp furnish closes and is: metallocene linear low density polyethylene 82 ~ 90%, thickening masterbatch 6 ~ 10%, anti-aging mother material 4 ~ 8%; The proportion relation of B layer raw material is: the metallocene linear low density polyethylene 90 ~ 94% being added with nano imvite, brightens shading masterbatch 6 ~ 10%; The proportion relation of C layer raw material is: metallocene linear low density polyethylene 92 ~ 96%, anti-aging mother material 4 ~ 8%.And the object adding thickening masterbatch is in the feed the surperficial tack in order to increase film, to prevent film in use due to tack pine bundle not, cause damage.The object adding anti-aging mother material is used to prevent the aging of film, strengthens its weatherability, extends its operating period.Add the light transmittance that the object brightening shading masterbatch is used to reduce film, rot to prevent the herbage in bale packing from carrying out too much photosynthesis.The object adding the metallocene linear-low density polyethylene of imvite is used to be to increase thin film strength.
Beneficial effect: a kind of herbage film that the utility model provides, take metallocene linear-low density polyethylene as a kind of plastic package material of primary raw material processing, it is strong that it has tack, puncture-resistant performance is splendid, anti ageing property is excellent, draw ratio advantages of higher, is suitable as the assembly package of herbage, can be used for storing herbage and playing fresh-keeping effect.Packing its distinguishing feature as herbage is: cost is low, and packaging efficiency is high, and the amount of labour used is few, and effect is very good, greatly reduces the waste of forage nutrition, improves the utilization rate of herbage, can shorten the marketing period of livestock, improves meat quality.
