Description
Water soluble membrane PVA soluble film main raw material polyvinyl alcohol and glycerin.
Water-soluble film as a new concept of environmentally friendly packaging materials, in Europe and the United States and Japan and other countries are widely used in water-soluble chemical products and in the use of internal packaging materials.
One: water-soluble Film Products
PVA Polyvinyl Alcohol series water-soluble film as a new concept of environmentally friendly packaging materials, in europe, america, Japan and other countries are widely used in water-soluble chemical products and in the use of internal packaging materials.
For example: pesticides, fertilizers, dyes, detergents, Water Treatment agents, Mineral additives, detergents, concrete additives, Photographic chemical reagents and garden care chemicals, etc., can also be used as
rapeseed, Plant seed bags, clothing bags, food and hospital washing bags and other products inside and outside the Packaging.
Second: The main characteristics of water-soluble films are as Follows:
1 with security packaging function is also used for quality products anti-counterfeiting of the best weapon, extend the life cycle of quality products;
2 environmental safety, 100% degradation, degradation of the final product is CO2 and h2o, no harmful substances produced;
3 safe and convenient to use, avoid direct contact with harmful substances by users;
4 can be accurately measured to prevent waste;
5 strength, toughness, Good plasticity, can be bonded, heat sealing performance is Excellent.
Three: the use of water-soluble film precautions
1 products containing more than 5% of the water is not suitable for the application of water-soluble film Packaging.
Environmental friendliness
PVA film products are green Environmental protection packaging materials, both non-toxic, and will not hinder the growth and reproduction of microorganisms, can be completely degraded. PVA material has two kinds of water and biological degradation characteristics, first dissolved in the water to form the liquid infiltration into the soil, increase the soil group viscosity, permeability and water retention, especially suitable for sand Reconstruction.
The PVA material in the soil can be decomposed by the strains of bacteria isolated from the soil, which can eventually degrade to CO2 and h3o. Water-soluble 1. Cold water soluble, soluble speed can be designed to choose, according to its dissolution rate is divided into: instant, medium soluble, slow dissolving three KINDS.
The dissolution rate depends on the water temperature and film thickness, the higher the water temperature, the faster the dissolution, and Vice Versa.
2. According to the appearance can be divided into smooth and embossed
3. According to color can be divided into colorless and colored (red, blue, yellow, green, etc.)
Safe PVA film avoids direct contact with toxic substances by users;
Transparency and Gloss
The degree of transparency and gloss of PVA film is superior to other Films.
Moisture Vapor Resistance
PVA membrane is similar to the moisture permeability of cellophane, is a very high moisture-permeable film, packaging hot and humid articles will not produce droplets. Water-soluble film moisture content will change with the environmental Humidity.
Usually the water-soluble film is packaged with PE film, keep its moisture content, when the water-soluble film removed from the PE film, moisture content will change with the environmental humidity, the performance has Changed.
At room temperature, its moisture content and environmental humidity changes such as table:
Barrier Resistance
PVA film on water and ammonia has a strong permeability, but the oxygen, nitrogen, hydrogen, helium, Argon and carbon dioxide and other excellent barrier, the use of PVA film can be intact to maintain the composition of the packaged product and its own Odor.
Anti-Static resistance Many plastic films have a strong electrical resistance, and PVA films are virtually non-static.
The use of PVA film packaging products in the process, will not be caused by static electricity and reduced plasticity or electrostatic dust.
and other thin film electrostatic parameters comparison Table:
Print Sex
PVA film polarity strong, good printing performance, can not be used when printing edm, has been widely used in special printing industry, such as water transfer film Substrate.
Strength and weather resistance
PVA film Strong toughness, tensile strength, anti-tearing strength of all types of film, its two-way tensile strength is superior, resistance to the number of twists and turns of other films 10 times times, good weather resistance, long service Life.
Mechanical Performance Table
Water and gas transmission rate Water-soluble film has strong permeability to water and ammonia, but it has good barrier to oxygen, nitrogen, hydrogen and carbon dioxide Gas.
These characteristics, so that they can be intact to maintain the composition of the packaged products and the original Odor. Oil-and Organic-solvent PVA films have excellent oil resistance (vegetable oils, Animal oils, mineral oils), fat-resistant, organic solvents and Carbohydrates.
however, Strong alkali, Strong acid, chlorine free radicals and other substances that can react with PVA (E.G. borax, boric acid, Some dyes, etc.), such substances are not suitable for PVA film packaging. 5 in the use of the product quality problems or other technical issues, please contact the supplier in time for the corresponding technical support
