Purpose

This machine is designed for tesign≥☆ed for testing the properties↔&₩≠ of heat seal of a poγ©lymeric film used as packing materi ÷al by controlling (1)tem ¥perature,(2)pressure(3)time.l<•n the actual heat seal productio×≤α←n line,these three elemφ↑ents are effectively ←©☆✔arranged to obtain an adequ'★ ate heat seal condition .but,atγδ the tesing and designing stages for  ®± packing materials,it is importan✘€t to promptly find an∑✔λ÷ adequate heat seal condition by the  •>∞composition of the materials and the ™¥type of sealant.Also，for quality control a♥'nd guarantee for production,measuremeεπ ♠nt of the heat seal strength of the pr♠επoduct is very important w¶$ork.Today,this machine is reco←♥≤€gnized and used as an indispensable > ® testing machine not only in the heλ εat pressure test of flexin✘Ω©♦le packing packing but aβφ ‍lso in the heat rasistance  ®♣>test of inks and hot-melt ad≤§hesives.
