What processes are recommended for M-Resin used for reclosable packaging?

The reseal M-Resins adhesives, a patented technology by Bostik can be converted on existing co-extrusion line without any significant investment. The resealable films can be used on existing packaging equipment by food producers with only minor adjustments.

Reseal M-Resin from Bostik can be processed on blown film line up to 9 layers including or not barrier material such as EVOH. Depending on the expected reclose performances, the thickness of Reseal M-Resin will vary from 12 to 15 µm.

How can resealable lidding packaging address sustainability?

Reseal M-Resins helps reduce plastic consumption, allowing up to 30% plastic reduction compared to clamshell packaging.

Official institutes have conducted tests and evaluations, confirming that Bostik M-Resin Adhesives do not impact the recyclability of PE film and APET tray:  

  •  “RECYCLASS concludes that Bostik M-Resins technology is compatible with the existing European Industrial recycling processes for PE flexibles”
  • “The PLASTIC SENSE FOUNDATION certifies that the adhesives “M-Resins manufactured by the company Bostik comply with the Recyclability Guidelines for Thermoformed PET Trays”

Resealable packaging contribute to reduce food waste by keeping the freshness of the food and by extending food shelf life.

What is the Dual System combining M-Resins and Vitel resins for resealable packaging?

Dual System combines the resealable feature with a sealing layer based on polyester from the Vitel®  range allowing the lidding film to be sealed on mono APET tray.

A such combination contributes to plastic material source reduction by eliminating the need of a multilayer tray and allows the recyclability of the APET tray complying with the Recyclability Guidelines for APET tray as follows:

“The PLASTIC SENSE FOUNDATION certifies that the following adhesives references M-Resins and Vitel® manufactured by the company Bostik, Inc. complies with the Recyclability Guidelines for Thermoformed PET Trays (attached in Annex 1) not disturbing the recycling process of thermoformed PET packaging and is, therefore, approved for its use in processes and products to be certified under ECOSENSE and RETRAY schemes supported by the Foundation”

VITEL®  is the trade name for high molecular weight, linear saturated co-polyester resins. It allows lower extrusion temperature vs. market standard, excellent compatibility with M-Resins, and lower heat activation.
