A thermoplastic resin, polyvinyl alcohol ( P-PVA )
Polyvinyl alcohol is a very wide application of environmentally friendly materials, but due to its melting point is 220 ℃, decomposition point is 240 ℃, hard thermoplastic processing, thus limiting its excellent performance of the play. After years of efforts, engineering and technical personnel to develop the success can be molten thermoplastic processing polyvinyl plastic resin, i.e. polyvinyl alcohol masterbatch, now in our company put into production.
Polyvinyl alcohol masterbatch can use ordinary film blowing machine, injection molding machine dry thermoplastic molding processing, production of water soluble film, biaxial stretching film and container, can also batch production of other types of degradable film. My company production of PVA masterbatch can be divided at room temperature, temperature, temperature three kinds, can fully meet the blown film and injection molding container with different needs, the products used in accord with the national standard the main raw materials and auxiliary materials processing and production of green color, transparent, non-toxic harmless. Good fluidity, stable processing performance, film thickness up to about 15 μ m thick, products such as mechanical strength than wet film improved by about one time, greatly reduce the integrated cost for unit. The products of different types of equipment, strong adaptability, convenient operation, high production efficiency.
Two, water soluble film
My company production of water soluble film in addition to the traditional wet production of water soluble film features, compared with it, also has the advantages of low energy consumption, good mechanical strength, high production efficiency, application of a wide range of products, low comprehensive cost, significant economic benefits, according to market of polyvinyl alcohol packaging water soluble film demand, have the following three types:
(1film ) at room temperature, it can be dissolved in water at room temperature, wide range of application. Can be used as pesticides, fertilizers, dyes, cleaning agents, water treatment agent, detergent, concrete additives and garden care chemicals.
(2) the temperature in the film, good transparency, bear large pulling force, uniform thickness, water soluble time is short, suitable for shopping bags, packaging bags and other special.
(3) high temperature type thin film, can be higher than 55 ℃dissolved in water. The product at room temperature and humid environment when in use to avoid moisture absorption or swelling, can be used in more areas of packaging.
The water soluble film products, a variety of specifications and models, and according to customer demand production of different thickness and width of the product.
Three, VCI film
Long-acting gas phase rust-proof series product is after years of concentrated research and development of environmental protection quality of packaging materials. The anti-rust products for a period of 1-3 years,3-5years,5-10years or even longer, can be used for all types of metal materials and related products packaging, rust-proof performance has reached the international advanced level; the green products, recyclable. The product is mainly applied to : military products, especially firearms and ammunition; mechanical parts, medical machinery, precision instruments, iron castings, aviation parts; a variety of hardware, powder metallurgy parts; all kinds of electric tools, measuring tools, cutting tools; bearings, clutch, motor, valve; automobile, motorcycle parts and components; all kinds of metal materials.
