Paper-based packaging with 100% recycled content and an uneven surface, such as our 100% Recycled Padded Mailers, can be difficult for labels and stickers to adhere to. This could result in having to cover shipping labels with clear plastic tape (making the entire package far more difficult to recycle). With this in mind, we are pleased to offer this high tack shipping label.
These shipping labels utilize a hot melt adhesive, which is 100% adhesive (no water). This makes for a stronger and more permanent seal than can be achieved through acrylic emulsion. Most labels, including UPS and DYMO labels, utilize acrylic emulsion adhesive (which are ~50% adhesive, ~50% water).
It is important to recognize that these are not a more sustainable option than standard labels. They are a solution designed to help companies ensure they can successfully use 100% recycled paper-based packaging that has an uneven or cushioned surface.
We recommend eco-minded companies test our our Zero Waste Shipping Labels (available as sheet labels and direct thermal), featuring a 100% recycled and curbside recyclable release liner, and only consider this high tack option if the zero waste labels have not been successful.
This direct thermal shipping label utilizes a STANDARD, silicone lined, virgin release liner that is not curbside recyclable. While it is not a sustainable shipping label alternative, it has an extremely high tack adhesive, allowing it to bond with difficult-to-adhere materials such as our 100% Recycled Padded Mailers. We are offering it as an option for companies that want to use Padded Mailers but haven't struggled to find a shipping label that works effectively for them.
