Description
Technical field
The invention belongs to polymeric material field, it is related to a kind of preparation method of antibacterial food PS packaging films.
Technical background
Plastic flexible packaging material, is generally referred to by plastics(Or plastic composite)Composition, soft texture, Ke Yitong
Cross the material that the modes such as bag, parcel are packed to commodity.In Soft Roll charging using it is most be various plastic sheetings and its
Membranaceous composite, fabric based packaging material etc..The extensive use of flexible packing material is the enterprises and institutions' list for being engaged in flexible package industry
Position provides extremely wide activity space, is also achieved higher than other plastics while excellent service is provided for users
The good benefit of processing and forming industry.Developed rapidly, prospect is very bright.Because the kind of flexible packing material is numerous
Many, performance span is very big, from performance it is similar, close to entirely different product have industrialized production.Flexible packing material is
Membranoid substance, thickness is fairly small, normally only 0.04um or so, every square metre quality only 0.025kg or so, therefore uses flexible package
Material commodity can significantly economize on resources consuming compared with other packaging materials.Not only consumption of raw material is small for plastic flexible packaging material,
And there is the comprehensive advantages such as easy to process, energy charge is low, shaping efficiency is high, thus have the advantages that cheap.Due to
Flexible packing material have the advantages that it is numerous, wherein the particularly pertinent reasonable combination that can be by various materials designs and manufactures
Desired, more satisfactory specific packaging material, thus with splendid cost performance, show the powerful market competitiveness
The extensive concern of people and the favor of user have been obtained, have developed rapidly, its application covers food, medicine, light industry, weaving, day
With all spectra of the almost industrial and agricultural production such as small item, it has also become one of most important kind in plastic package material.
Different plastics can be not only used in flexible package plastics, using different formulations, pass through different process manufacturing property
Different various single thin films, but also can obtain hundreds of different by the various combination between multiple material
Kind, meets a variety of needs.The characteristics of using different flexible packing material different properties, can by the reasonable selection of kind
The demand of numerous commodity packagings can be met.Polystyrene film is to be easiest to one of film of stretching orientation, and PS films are because transparent
Degree is high, is often used as the window material on packing box.It is suitable to thermoforming, and various bowls, disk etc. can be made as packing timber
Material, original of the polystyrene film suitable for packing some fresh food such as fish, meat, vegetables etc. for having respiration storage process
Because being:The characteristics of polystyrene film is that transparency is high, and good stability of the dimension is nontoxic, still, harder, is a kind of gas permeability ratio
Preferable film, thus suitable for some fresh food such as fish, meat, the vegetables etc. for having respiration storage process of packaging.
But so also cause virus and mould to be easily attached to the surface of biodegradable plastic, therefore have the doubt of safety and health.For
This, we set about from the formula and technique of product, develop new high performance material, research and develop a kind of the new of antibacterial food PS packaging films
Technique is the task of top priority of whole industry.
