Abstract

The invention discloses a grain preservative film of modified-atmosphere packaging for rat control which contains capsaicin microcapsule. The film is prepared by components of polyethylene resin, polyvinyl acetate, zinc stearate, calcium stearate, light calcium carbonate, white carbon black, paraffin wax, antioxidant and fluorescent agent. The components are weighed and mixed proportionally, extruded by a single screw plastic extruder, and subject to blow moulding to prepare a film. Capsaicin microcapsule, as a raticide, is coated on outer surface of the plastic film by an adhesive to prepare grain preservative film of modified-atmosphere packaging for rat control. The raticide slowly and continuously releases, thus achieving objective of long-term effective rat control, and has bidirectional atmosphere modifying function on O2 and CO2, with good moisture permeability of small packages, good antifogging and antisweat performance and oxidation resistance and anti aging ability.

Description

technical field [0001] The invention belongs to grain fresh-keeping film, in particular to a special fresh-keeping film (bag) with functions of anti-rodent and air-conditioning - grain anti-rodent modified atmosphere fresh-keeping film and a manufacturing method thereof. Background technique [0002] At present, there are many new technologies for the preservation of agricultural products, such as preservatives and plastic wraps. All preservatives and preservative films are selectively used for fresh-keeping objects, that is, different types of agricultural products need to use fresh-keeping technologies with different functions. Also there is no fresh-keeping film or fresh-keeping bag specially aimed at grain anti-rodent fresh-keeping. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grain rodent-proof modified atmosphere fresh-keeping film and its production method, which is suitable for the use of grain rode...
