Frequently Asked Questions

For paper craft techniques such as Collage, Decoupage, or Paper Mache, we recommend using Aleene's Premium Decoupage Glue. This glue is also ideal for DIY projects including greeting cards, gift wrapping, scrapbooking, stamps, and posters. Available in Matte and Gloss finishes, Aleene's Premium Decoupage Glue works well on paper, cardstock, cardboard, tissue paper, wood, terra cotta, canvas, glass, plaster, styrofoam, foam sheets, and embellishments like ribbons, glitter, iridescent mica powders, and fabric.

Application Instructions:

• Apply the Decoupage Glue onto the substrate surface with a paintbrush, sponge, or foam dauber.
• While the glue is wet, place the glued items (such as tissue paper and embellishments) onto the substrate surface.
• Smooth out the glued items with your finger to remove air voids.
• Let the glue dry completely or apply another coat as a sealer.
• Clean up any excess with a damp cloth.
• Allow the item to dry fully for 24-72 hours before handling.

Additional Information:

This glue offers UV and moisture resistance, making it durable even under some outdoor conditions without yellowing or deterioration.

Polyvinyl Alcohol (PVA), also known as PVOH or PVAI, is a versatile water-soluble synthetic polymer. It finds applications across various industries. But what exactly is PVA and where can you find it? Recent studies have tried to uncover the truth about PVA's environmental impact and its role in laundry detergents.

Understanding PVA

PVA is a biodegradable, odorless, and colorless synthetic polymer resin discovered in 1924 by German Nobel Laureate Dr. Hermann Staudinger. It became commercially viable in 1950 in Japan, thanks to Kuraray's development of mass production techniques. PVA is known for forming strong, flexible films with high tensile strength and good barrier properties. It is also non-toxic, making it suitable for food packaging and other human contact applications.

One of the distinctive features of PVA is its water solubility, which makes it ideal for water-soluble films and packaging. This material is used in a variety of products, including contact lenses, medicine capsules, fishing lines, papermaking, photographic film, and eye drops. Commonly, PVA is utilized in laundry detergents for encapsulating detergent pods and forming detergent sheets, dissolving in water to release the cleaning agents safely into the environment.

Pros and Cons of PVA

Pros:

• Biodegradability: PVA can decompose naturally, posing no harm to the environment.
• Water Solubility: Its solubility in water makes it versatile for adhesives, coatings, and films.
• Strong Adhesive Properties: PVA adheres well to materials like paper, fabrics, and wood.
• Low Toxicity: It is safe for use in food packaging and other consumer products.
• Versatility: PVA can be modified for varying properties like elasticity and strength.

Cons:

• Poor Resistance to Heat and Moisture: This limits its use in high-temperature or humid environments.
• Limited Chemical Resistance: PVA is sensitive to certain chemicals, degrading its properties.
• Brittleness: Over time, PVA can become brittle.
• Slow Drying Time: Its slow drying time may not suit some applications.
• Cost: PVA can be relatively expensive compared to other adhesives and polymers.

PVA and Microplastics

Microplastics are tiny plastic debris less than five millimeters long, significantly polluting the environment. They come from various sources, including face masks and synthetic fabrics, and often break down into even smaller particles that can become airborne. This poses an ingestion and inhalation risk to humans. An estimated 74,000 to 114,000 microplastics are consumed or inhaled by humans annually.

Unlike microplastics, PVA films dissolve in water and are biodegradable. Water treatment facilities and environmental microorganisms can degrade these dissolved polymers, reducing PVA's impact compared to non-biodegradable microplastics.

PVA's Environmental Safety

PVA films are safe for the environment due to their water solubility and non-toxic properties. Used in detergent sheets or pods, PVA dissolves entirely in water, breaking down in wastewater treatment facilities. EWG's Skin Deep rates polyvinyl alcohol at level 1 on a scale from 1 to 10 for environmental and human impact, indicating minimal risk.

Misconceptions and Misinformation

Some companies have spread misinformation about PVA to promote their own products. The American Cleaning Institute (ACI) has countered these claims, emphasizing the extensive research supporting PVA's safety and biodegradability. Many non-governmental organizations continue to release unfounded information to disrupt innovative uses of PVA in the laundry industry.

PVA in Kind Laundry Products

Kind Laundry detergent sheets contain PVA to maintain their structure. Recognized by the FDA as safe, PVA in Kind Laundry products is biodegradable and completely dissolvable. Transparency and education about product ingredients remain a core focus for Kind Laundry.

Conclusion

Polyvinyl Alcohol (PVA) is an invaluable synthetic polymer with numerous benefits and a few drawbacks depending on its application. Its biodegradability, low toxicity, and effective adhesive properties make it a preferred choice in various industries, including food packaging and laundry detergents. However, its limited resistance to heat and brittleness over time must be considered. When employed correctly, PVA proves to be a safe and effective material for many industrial applications.
