Quick flowing adhesive delivers high initial adhesion for faster lamination

0.5 mil PET film carrier adds dimensional stability and easier handling during slitting and die-cutting

3M™ Adhesive 300 aggressively bonds to many surfaces, including plastics like polyethylene

55# 3.2 mil densified kraft liner makes for easy release

3M™ Double Coated Tape 444 features 3M™ Adhesive 300, a medium-firm acrylic adhesive ideal for joining materials that are smooth, thin and have low residual stress. It is excellent for foams and LSE plastics such as polyethylene, as well as HSE plastics. Adhesive is applied to both sides of a 0.5 mil PET film which adds structural stability. This tape features a 55# densified kraft liner.

A Double Coated Tape for Foams and LSE Plastics
Excellent for textured plastics, foams, fabrics and coated papers, 3M™ Double Coated Tape 444 features 3M™ Adhesive 300 on a 0.5 mil polyester (PET) film carrier. The medium-firm acrylic adhesive delivers high initial and final adhesion for efficient laminating procedures. The durable polyester film carrier between the adhesive layers improves the handling and strength of the tape, and adds stability during processes such as die-cutting and slitting. The adhesive is applied at 1.4 mils on the liner side and 2 mils on the face side for effective wet-out. The 55# densified kraft paper release liner makes for fast, efficient application.
