Product description

Bags made with polyvinyl alcohol (PVA), which is a fossil-based polymer. In contact with humidity, rain and oxygen the PVA is biodegradable, turning into a natural compost for land.

Our bags made of water-soluble materials are those that minimize the impact with the environment, since they are made of totally biodegradable materials, so if for any reason these materials end up in contact with nature as waste, they end up decomposing in a matter of hours or days depending on their formulation.

It’s recommended that they are consumed within 12 months. They should be stored very carefully, maintaining constant room temperature and avoiding humidity and direct sunlight. They are not suitable for all applications because of their water solubility.

Characteristics of Rovi Packaging’s water-soluble plastics:

• Fossil-based polymer.
• Biodegradable: this polymer is decomposed into CO2, water and other basic molecules, becoming totally integrated in the environment.
• They are soluble in water: for this reason they are not suitable for all applications.
• Non-toxic: once decomposed, they are fully integrated into natural cycles without leaving a mark on the environment.
• Compostable: they behave like organic waste, allowing them to be transformed into natural fertilizer.
• Customizable: they can be printed with inks that are degradable and innocuous to the environment.
• We have three types of formulations depending on the temperature of the water at which the material is soluble, so it is classified as
  • CD: soluble from 45℃
  • MD: soluble from 65℃
  • HD: soluble from 85℃
• Film thickness from 25 to 80 microns.
• All our products have biodegradability and non-toxicity certificate.

1. Changzhou Green Cradleland Macromolecule Materials Co.,Ltd (hereinafter referred to as the company) was established in 2011 and focuses on the research and development and production of film-grade, fiber-grade and injection-grade water-soluble biodegradable materials.

2. The company is the most comprehensive domestic enterprise that produces PVA water-soluble films, water-soluble bags and other products using the melt method + dry film blowing technology. The products are divided into three categories:
a: Room temperature water-soluble degradable film (dissolves when exposed to water)
b: Medium temperature water-soluble degradable film (insoluble in room temperature water, completely dissolved in 60 degrees water)
c: High temperature water-soluble degradable film (insoluble in 45 degrees water, completely dissolved in 80 degrees water)

3. Experienced R&D team, several engineers and professional technicians

4. Complete product testing and quality assurance system, leading the industry in water-soluble film related products

5. In addition, we also provide:

a: PVA (polyvinyl alcohol) film production plant planning
b: PVA (polyvinyl alcohol) film production technology, equipment, process output
c: PVA (polyvinyl alcohol) film turnkey project engineering

PVA is a water-soluble polymer material. It uses water-soluble polymer as the film-forming matrix, and adds auxiliary materials such as plasticizers, softeners, surfactants, dispersants, etc. It is made through a specific film-forming process. The film has good flexibility and isolation to various substances, and dissolves quickly in water.
Application areas:

a. Inner packaging bags for pesticides and chemical products
b. Cement additive packaging bags
c. Disposable aprons
d. Hospital washing packaging bags
e. Disposable gloves
f. Disposable tablecloths
g. Water-soluble and degradable shopping bags
h. Inner packaging bags for home appliances
i. Embroidery film for clothing accessories
