The water-soluble film blow molding machine is an advanced level in the PVA field in terms of mixing, granulation, blown film forming technology and production process.
Water soluble PVA film is a new type of green and environmentally friendly packaging material developed in recent years. It has the dual characteristics of water solubility and biodegradation, and can be completely degraded into carbon dioxide and water. It has a wide range of applications and good market prospects in the flexible packaging industry.
Main technical features
1、 Specialized screw, specialized extruder, specialized control system II, specially designed molding head
3、 A dedicated auxiliary molding system with a reasonable and compact structure, easy operation, and strong practicality.
Introduction to the application fields and products of water-soluble films
Embroidery aspect
Water soluble PVA film can be used as a temporary carrier in the production of wigs and embroidery.
In terms of embroidery, due to the water solubility of PVA film used as a cushion, it only needs to be soaked in room temperature water for a few minutes, and the cushion material will completely dissolve, and the embroidery pattern can be presented.
The advantages of using water-soluble PVA film are: non-toxic, fully soluble, easy to handle, and no residue such as wire drawing or adhesive buildup; Suitable for multi head embroidery machines, it will not break or deviate from the hole position; Replace non-woven fabric padding to avoid deformation of textiles and fading of fiber dyes during high-temperature dissolution.
● In terms of agriculture
The packaging tape containing seeds made of water-soluble PVA film can be used for sowing crops (such as radishes, onion heads, carrots, and various plant and flower seeds), which can improve the efficiency and accuracy of sowing, and enable plants to grow according to the sowing shape of the seed tape or seed net, avoiding seeds from being exposed and blown away or eaten by animals in windy and sandy areas. After rainwater or moisture dissolves the water-soluble PVA film, the seeds can germinate and grow in the soil.
● Chemical packaging
The waste packaging of pesticides, fertilizers, and various pollutants has become a major public hazard, and PVA film packaging bags have been widely used in the packaging of pesticides, fertilizers, additives, and dyes due to their good water solubility and mechanical strength.
● Anti infection and disinfection packaging
In hospitals, high-temperature water-soluble PVA film packaging bags can be used to package and isolate contaminated products and clothing. During disinfection and cleaning, the packaging bags containing pollutants can be directly put into the cleaning and disinfection equipment for cleaning, reducing the contact of medical staff with contaminated products and clothing during transportation, storage, and cleaning, avoiding the spread of bacteria, and preventing secondary bacterial infections in hospitals.
● Textile packaging
Compared with general packaging materials, using PVA film to package textiles has the advantages of no static electricity, transparency and glossiness, and better hand feel than other packaging materials, making the packaged objects present a more vivid and clean appearance, and improving the value of the product. Due to its high air barrier properties, PVA film can block nitrogen gas in the air when used for textile packaging, preventing textiles from easily turning yellow.
● Food packaging
Due to the excellent gas barrier and oil resistance of PVA film, these characteristics can greatly extend the shelf life of packaged food and maintain its composition and odor intact.
● Demoulding packaging
PVA film can be used as a high-performance release agent when making parts using unsaturated polyester, epoxy resin, or other thermosetting resins.
Packaging of electronic products
Due to the fact that PVA film carries almost no static electricity, it is suitable for packaging electronic products such as integrated modules. Products packaged with PVA film do not absorb dust in the air due to their lack of charge, which improves the cleanliness and aesthetics of the packaged products.
● Water to printing aspect
Water soluble PVA film can be used for trademark and pattern transfer printing on irregular surfaces of ceramics, plastics, metals, and wooden items, such as electrical casings, automotive peach wood, mobile phone casings, etc.
● Packaging of daily necessities
Due to its unique properties and environmental friendliness, PVA film has been widely used in daily necessities packaging. For example, detergent packaging and eco-friendly shopping bags.
