Mechanical property of the thin film and sealing
Surface thickness: 200-300μm
Breaking strength: 3-6N/mm
Elasticity(elongation): 250-900%
High frequency sealing, breaking strength: 1.5-3.5N/mm
Hot-press sealing, breaking strength: 0.75-2N/mm
Chemical property
=˃ PVC TA （ polyvinyl chloride, sky blue and semitransparent）
=˃ PVC colorlesss and transparent（cristal)，0.15-0.48mm
★★Strong acid, strong base, other solvent, oil and fat
★Aromatic solvent and ketone
★Weak ★★Neutral ★★★Strong
=˃ EBA/EVA （ethylene、butyl、hexenoic acid/ ethylene、ethenyl、acetic acid）
=˃ PUR（polyurethane），0.2mm 、0.3mm
Good chemical stability when EBA/EVA thin film contacts with the (sodium hydroxide, Sulfuric acid, nitric acid, ethanol) solvent
EVA thin film and PUP thin film can be incinerated, don’t contain lead, heavy metal, phosphorus or halogen
