Biodegradable PVA Film Series

 

Cold water soluble film as a kind of new environmental protection film material, because of its special properties, are widely used in packaging, soluble embroidery, printing, mold release agents, temporary liner, and other fields, greatly facilitate the industry and people's everyday life.

Small make up today and all of you take a look at the characteristics and application of water soluble film at low temperature field:
& have spent
 
1.

According to the characteristics of water soluble film temperature is adjustable, can produce instant at low temperature, high temperature type water soluble bags.

 
 
 
2.

Dissolve bags at low temperature is mainly used for chemical products of quantitative packaging for one-off delivery.

 
 
 
3.

High temperature dissolving packaging and packaging of export products is mainly used for clothing.
Water soluble film.

 
 
 
4.

According to the weight of packaged goods, volume, shape to conform to the requirements of the specification.

low temperature water soluble film products as high-tech environmental protection material, has the following features: water soluble and water soluble speed can be designed, non-toxic pollution-free;

The tensile strength, tension, etc. With equal or better than traditional plastic film;
High transparency, good gloss.
Good resistance to oil solubility, heat sealing, printing;

Good antistatic performance, mainly used in computer embroidery, water transfer printing and product environmental protection packing.


that is about the characteristics and application of water soluble film at low temperature field, thanks for your reading, I hope you can like it, want to further understand the friends can access the company website or call us, we will provide you with quality service

the people environmental protection consciousness enhancement for manufacturers to see the chances of biodegradable plastics in the packaging market.

Many international well-known manufacturers have entered the market in the form of mergers and acquisitions, joint ventures.

Given the current consumer awareness of biodegradable plastics is not high, the future will also need to foster the market, guide the consumers to accept this kind of environmental protection material, biodegradable plastics development prospect.
Today, & other;
The sustainable development of the packaging & throughout;

As a term is no longer the packaging quality judgement according to the sustainable development of packaging industry in the future should concentrate on practicability and sustainability after use, rather than the packaging itself.

For packaging industry is moving toward efficient products, high efficient packing, efficient transport efficiency and efficient solutions are the four main aspects, such as all-round development.

As the intelligent packaging, not the source of petrochemical plant plastic, drive the development of packaging will make the whole supply chain more efficient, and effective packaging solutions.

This is a very big progress, many small businesses and corporations have invested heavily in its recoverable after packaging supply chain and used, thus more & other;
Sustainable & throughout;
That phrase & other;
Sustainable packaging & throughout;
Will also cease to exist.

Now some people in the society is the plastic products group, it does not accept any form of plastic packaging products, sustainable packaging products and very suspicious.

Packaging industry experts joann haines said, as the industry enterprise, if you want to get more consumers, change their prejudices, make sustainable packaging industry gets more broad space for development, it should pay more attention to consumer cognition, packaging and practicability, the biggest sustainability throughout the supply chain and recyclability after use, etc.

u003cbru003e How to identify the quality problems of water-soluble film products, it is recommended to consider the following aspects. u003cbru003e 1. Water solubility: u003cbru003e The cold water soluble film requires that it can be dissolved in water above 5℃. The faster it melts, the better. u003cbru003e The less residual residue after dissolution, the better. u003cbru003e The clearer the water after dissolution, the better. u003cbru003e 2. Appearance quality: u003cbru003e The smoother the winding, the better. The outer surface of the winding should not have obvious unevenness and wrinkles. The two end faces of the rolled film should be as smooth as possible, within ±5mm. The surface of the film must not or have few defects such as bubbles, perforations (except for cross-stitch water-soluble film), slag inclusions, black spots and other defects. u003cbru003e 3. Mechanical strength: u003cbru003e The tensile strength is required to be above 25Mpa (related to the thickness of the film, the thicker the greater the tensile strength). Too little is easy to pull off. u003cbru003e The higher the elongation at break, the harder the film, and the smaller the softer the film. u003cbru003e The right-angle tear resistance is required to be around 80KN/m. Otherwise it will be brittle when broken. u003cbru003e Four, storage time: u003cbru003e The storage time of water-soluble film with stable quality can be more than 1-2 years when stored in a sealed package without moisture. u003cbru003e If the poor quality water-soluble film is stored for less than 6 months, due to the unstable quality, many chemical components will precipitate out of the film, and a lot of white dust will appear, and the severely rolled film will turn dark.

Optical grade polyester film has excellent optical properties such as low haze and high light transmittance, high surface finish, and small thickness tolerance. It is mainly used for diffusion film, brightness enhancement film, reflective film and antistatic protection in high-end liquid crystal display equipment. Films, protective films in touch panels, and films for flexible displays, etc. Among the upstream raw materials of liquid crystal panels, optical films are used in backlight modules, polarizers, and liquid crystal materials. Liquid crystal display is the current mainstream flat panel display technology, which is widely used in fields such as LCD TVs, notebook computers, monitors, and mobile phones. In the entire tft-lcd production process, the total required area of u200bu200bthe optical film is about 15-20 times that of the panel, and the cost is about 15-20% of the LCD panel. China is becoming the world's largest producer of flat panel display equipment. At the same time, the explosive growth of the domestic touch screen industry has prompted a rapid increase in the demand for optical films. Optical films have become one of the most important strategic raw materials at the front end of the optoelectronic industry chain. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide variety of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, and warm and thoughtful service.
