Pre-heat paper in a dryer to 260 F (132 C), then print immediately to maintain registration, or cover with plastic sheeting.
Remember to continue to keep the transfer paper in plastic wrapping or in a temperature controlled oven, as moisture will invariably be absorbed by the paper between each printed color.

Cesa™ Laser Additives Laser welding solutions Laser plastic welding, also often referred to as transmission welding, is a process of bonding plastic parts using focused laser radiation.
A laser beam is directed onto two plastic parts, one that is transparent to the laser energy and one that absorbs the energy.
Solutions are available for the laser welding of transparent/black, transparent/color, color/color, and black/black parts.

According to projections, the world may produce over 400 million tons of plastic waste annually by 2030 (National Geographic).
Recycled plastics can be used to create new products across several industries, but one brand owner in particular was looking to incorporate recycled plastics in their consumer applications.
