In the world of plastic extrusion and thermoforming, slip and denesting characteristics are essential. Without it, sheets stick during production, and finished containers become impossible to denest, leading to downtime and frustrated end-users.
For decades, silicone-based coatings have been the industry standard for reducing the Coefficient of Friction (COF). However, silicone can be a double-edged sword. As packaging demands evolve, the “standard” silicone solution is becoming a primary source of failure.
3 Ways Silicone Hurts Your Process
- Seal Integrity: Silicone is designed for “release,” which is the enemy of adhesion. During thermoforming, silicone can migrate to the container flange, preventing lidding films from bonding. This leads to weak or no seals, inconsistent bonds across trays, and compromised food safety
- Ink Adhesion: Silicone is notorious for lowering surface energy, which creates a “non-stick” environment that quality inks can’t penetrate. This results in ink beading/crawling, poor or no adhesion and ruins the clarity of vibrant colors
- “Tea Staining” Effect: At high extrusion or thermoforming temperatures, silicone and its emulsifiers can thermally degrade. This creates a yellowish-brown residue known as “tea staining,” which ruins the clarity of the sheet and causes buildup on expensive molds
The Solution: ACC ProSlip
You don’t have to sacrifice sealability for slip. Our ACC ProSlip is a formulated coating engineered to deliver superior denesting and COF values without the side effects of silicone.
- Sealability: No migration, meaning lidding films bond perfectly every time
- Printing Ink Ready: Maintains the surface energy needed for vibrant, permanent ink laydown
- Thermal Stability: Eliminate tea staining and keep your sheets and parts crystal clear
You shouldn’t have to trade everything for slip. If you’re tired of chasing silicone related QC issues, ask us how our ACC ProSlip can help you!
