PTFE glass Tape, self adhesive Teflon tape for Heat Sealing
PTFE glass tape with silicone adhesive also called PTFE adhesive tape combines benefits of PTFE, fiberglass and pressure sensitive silicone adhesive, the tape is coated with PTFE resin, PTFE coating makes surface of the tape non-stick and quickly release function, basic material of this tape is fiberglass which gives the tape high strength and dimension stable, backed adhesive is using silicone adhesive imported from USA, the adhesive will increase stickiness during high temperature and resist heat up to max 260°C(500℉). Thickness of Teflon adhesive tape varies from 3mil to 14mil (0.08mm to 0.35mm).
Teflon adhesive tape gives benefits as below:
l High and low temperature proof
l Smooth friction performance
l High mechanical strength
l Non stick surface, provide optimal mold releasing
l Good thermal insulation
l Flame retardant
Specifications of PTFE Adhesive
Thickness: 3mil, 5mil, 7mil, 10mil, 14mil
Width: Standard width are 1000mm and 1250mm, small width can slit
Length: Normally 10m or 3m0 for small rolls; 40m or 50m for jumbo rolls
PTFE glass tape can be with yellow release paper on the back, or without release paper on the back. (Please let us know if you need release paper when ordering)
Teflon adhesive tape in small rolls without release paper on the back is typically used in packaging industry, common sizes include 13mm x 10m, 19mm x 10m, 25mm x 10m. This Teflon heat tape are used in a variety range of packaging way include heat shrink film packing, blister packing, form and fill packaging.
3mil Teflon heat seal tape is suitable for this application because it allow quick transfer of heat from the heating element surface through the tape to make the seal successfully.
Due to its nonstick property, the packaging material surface will be protected without being damaged.
As a barrier between heating element and packaging product, the tape will prevent melted packing material being stuck on the heating element.
If you want a texture impression to be left on your packaging part, Mutiflon also have PTFE glass tape in rough surface, unlike the smooth PTFE coated glass tape, there will be texture surface on this tape and the texture will transfer to the product during heat sealing.
