example 1

[0034] Make functional masterbatch first:

[0035] 10% short-term anti-fog functional masterbatch (10kg anti-fog material + 90kg polyethylene resin)

[0036] 20% antibacterial functional masterbatch (20kg antibacterial material + 80kg polyethylene resin)

[0037] It is completed by co-rotating parallel twin-screw extruder unit, and the operation process is as follows:

[0038] Masterbatch material

[0039] + Weighing → mixing → metering feeder → twin-screw extruder → strand cutting → masterbatch products

[0040] Base resin

[0041] Then carry out film and bag forming, using Φ50mm single-screw clip chain self-sealing bag film blowing machine and automatic bag making machine to complete, the operation process:

[0042] Base resin

[0043] + Weighing → plastic particle mixer → automatic feeding device → zipper ziplock bag film blowing machine → blowing

[0044] Auxiliary filler

[0045] Plastic film → printing → automatic bag making machine → (punching) → fin...

[0054] The formula can take

[0055] Linear polyethylene resin (LLDPE) 40-50 kg

[0056] Low-density polyethylene resin (LDPE) 20-25 kg

[0057] Ethylene-vinyl acetate resin (EVA) 16-20 kg

[0058] 10% short-acting anti-fog functional masterbatch 5-10 kg

[0059] 20% antibacterial functional masterbatch 4-8 kg

[0061] The best formulations are:

[0062] By weight,:

[0063] Linear polyethylene resin (LLDPE) 48 kg

[0064] Low-density polyethylene resin (LDPE) 24 kg

[0065] Ethylene-vinyl acetate resin (EVA) 15 kg

[0066] 10% short-acting anti-fog functional masterbatch 8kg

[0067] 20% antibacterial functional masterbatch 5 kg.

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.
