Performance meets responsibility with these window envelopes manufactured with film that provides an environmentally responsible, biodegradable alternative.
At SupremeX, we recognize that businesses and consumers are increasingly seeking solutions that balance functionality with environmental responsibility. Our EnviroSafe™ envelopes have been carefully designed to meet this demand, offering the same reliability and appearance as traditional window envelopes while reducing their long-term environmental impact.
A key feature of EnviroSafe™ envelopes is the use of 22DG Matte Polystyrene window film with prodegradent technology. Unlike conventional window materials, this film is engineered to gradually lose its physical properties over time, enabling accelerated erosion once it reaches the end of its useful life. The result is a window that maintains performance in use, but is designed with the environment in mind.
Key Environmental Advantages
- Recyclable: The 22DG window film is compatible with existing recycling streams, ensuring that the envelope can be processed without requiring special handling.
- Reduced Waste: By breaking down more efficiently after disposal, the film helps minimize long-term waste accumulation.
- Post-Industrial Recycled Content: Each window film contains up to 25% recycled material, giving new life to otherwise discarded resources.
- Tested & Verified: The film has been substantiated by independent third-party testing under ASTM standards (D6954-04, D5208-09, D5338-11), ensuring credibility and compliance with industry benchmarks.
Technical Strengths That Support Performance
While EnviroSafe™ envelopes are eco-forward, they also maintain the durability and clarity needed for everyday business communication. The 22DG film offers:
- Excellent stiffness for smooth converting and reliable high-speed inserting.
- Outstanding processability with current inks and adhesives, ensuring no compromises in print quality or sealing.
- Chemical resistance to acids, alcohols, fats, and oils—keeping the window intact during handling.
- FDA compliance (CFR 21 #177.1640), making the film suitable for applications where regulatory safety is essential.
- Controlled lifespan of approximately five years, balancing usability with environmental stewardship.
Typical Film Properties
- Gauge: 115 ga / 29.21 µm
- Yield: 26,360 in²/lb (37.43 m²/kg)
- Tensile Strength: 8,000 – 12,000 psi
- Ultimate Elongation: 3 – 10%
- Tensile Modulus: 400,000 – 450,000 psi
These technical properties mean that EnviroSafe™ envelopes perform seamlessly in the real world, offering both the operational efficiency customers expect and the sustainability benefits they increasingly demand.
