Abstract
The invention relates to a fruit and vegetable shelf small package bag film which is prepared from the following raw materials by weight parts: LLDPE (Linear Low Density Polyethylene), LDPE (Low Density Polyethylene), EVA (Ethylene/Vinyl Acetate), 10 percent of short-acting antifogging functional master batches and 20 percent of antimicrobial functional master batches. A manufacture method of the fruit and vegetable shelf small package bag film comprises the following steps of: weighing the raw materials according to the proportions; mixing by a plastic particle mixer; and blowing, molding and filming by adopting a self bag-sealing film-blowing machine with a clamping chain in the diameter of 50 mm. The product is suitable for packaging fruits and vegetables, such as grapes, cherries, hawkthorns, kiwifruits, apples, peppers, carrots, edible fungi, and the like, is non-toxic and transparent, and accords with the food safety standard. Because of indirect contact with the external environment (air, human contact, and the like) in the shelf life period, fruit and vegetable products packaged by the small bags can avoid the pollution of a certain harmful microorganisms (various bacteria) and lessen loss caused by withering dehydration, mechanical damage, and the like. Meanwhile, the invention has the effects of resisting aging and prolonging the shelf life and can improve the marketability of fruit and vegetable products by 2-5 days.
Description
Technical field
The invention belongs to vegetable and fruit packaging, particularly a kind of fruits and vegetables shelf small package bag film and making method.
Background technology
Although fruits and vegetables have also used some wrapped products at shelf-lives at present, but because characteristics such as physiological property of self and face shaping after not adopting according to fruit and vegetable food, different fruit and vegetable foods should use different designs and making method, thereby, do not reach purpose and effect that fruit and vegetable food is packed, cause losses such as fruit and vegetable food dehydration or mechanical injury, to such an extent as to the Insecure Packing breakage causes the needs of fruit and vegetable food secondary pollution.
Summary of the invention
Technical problem to be solved by this invention is: a kind of fruits and vegetables shelf small package bag film and making method are provided.In the shelf-lives sales section, reduce the loss and prevent that staff from directly touching the needs that cause secondary pollution to satisfy some fruits and vegetables.
Technical scheme of the present invention is:
A kind of fruits and vegetables shelf small package bag film is characterized in that:
Its constitutive material composition: by weight, its composition is:
40～50 parts of linear polyethylene resin LLDPE
20～25 parts of ldpe resin LDPE
16～20 parts of ethylene-vinyl acetate resin EVA
5～10 parts of 10% fugitive anti-fog function master batches
4～8 parts of 20% antibacterial master batches
Claim batching according to the above ratio, behind plastic pellet mixing machine mixing, adopt the film forming of 50mm clip chain valve bag inflation film manufacturing machine equipment blowing.
Its optimum formula is:
By weight, fill a prescription and be:
48 parts of linear polyethylene resin LLDPE
24 parts of ldpe resin LDPE
15 parts of ethylene-vinyl acetate resin EVA
8 parts of 10% fugitive anti-fog function master batches
5 parts of 20% antibacterial master batches.
Fruits and vegetables shelf small package bag film and making method:
By above-mentioned agglomerate material and substrate resin components in certain proportion batching, mix, adopt cocurrent and parallel twin screw extruder group to make the master batch product; Adopt single screw rod clip chain valve bag inflation film manufacturing machine of Φ 50mm and automatic bag making machine to finish film and bag forming again.
Effect characteristics of the present invention are:
1, this product is applicable to fruits and vegetables such as grape, cherry, hawthorn, Kiwifruit, apple, capsicum, Radix Dauci Sativae, edible mushrooms;
2, wrapping material are nontoxic, transparent, meet food security standard;
3, at different fruit and vegetable food characteristics, can adopt multi-form, specification packing, improved product self class and commodity value;
4, the fruit and vegetable food behind small packages at the shelf circulation period, owing to directly do not contact external environment (air, staff touch etc.), can reduce the pollution of some harmful microorganisms (various bacteriums etc.);
5, fruit and vegetable food is through behind the small packages, can reduce the here dehydration (as the green pepper elephant skin) of withering, mechanical wounding
The loss that (as the grape threshing) etc. causes, the effect that delaying senility is also arranged simultaneously and prolong shelf-lives can increase the commodity 2～5 days of fruit and vegetable food.
Fruit and vegetable food small packages effect example:
Preservative film is to the influence of fruits and vegetables shelf fresh keeping time (room temperature 20 ℃ under deposit)
Embodiment
Fruits and vegetables shelf small package bag film and making method
Example 1
