LDPE
Sensory identification: soft touch 5261; 4102 white transparent, but generally transparent, often tape 1653 and printed words. (Note: tape and print are unavoidable, but the content must be controlled as these will affect the market price). When burning smokeless, there is the smell of paraffin wax, molten dripping, easy to draw wire.
HDPE
Sensory identification: rough feel; White transparent or opaque, transparent, often tape and printed words. (Note: tape and print are unavoidable, but the content must be controlled as these will affect the market price). When burning smokeless, there is the smell of paraffin wax, molten dripping, hard to draw wire.
EVA
Sensory identification: soft surface; Elongation toughness than LDPE, feel sticky (but no surface glue); White transparent, high transparency, feel and feel very similar to PVC film should be distinguished. Combustion identification: the smell of paraffin wax is slightly sour as that of LDPE. The burning flame is yellow and blue; Smoke when you burn. Melt dripping, easy to wire drawing. Note: this product is one of PE types, the price is the same as LDPE, it can be used for regeneration granulation, the quality requirements are the same as PE.
