Beschreibung
Zusammenfassung:	The invention discloses a production process of a PE/PP composite suitable for coating of non-transfer adhesive, which is characterized by comprising the steps of (1) carrying out antistatic and anti-aging modification on a PP material to prepare PP modified master batch; (2) manufacturing a nonwoven fabric with the PP modified master batch obtained in the step (1); (3) hot-rolling the nonwoven fabric through a hot rolling mill; (4) mixing LDPE (low-density polyethylene) and LLDPE (linear low density polyethylene) according to a certain proportion, and then preparing a PE film mother liquor; (5) laminating the PE film mother liquor prepared in the step (4) to the nonwoven fabric; (6) applying corona to the composite film obtained in the step (5) to ensure that the surface tension of the film meets the gluing requirement; and (7) rolling the composite film obtained in the step (6) under tension control and cooling temperature control so as to control the cover flatness of the fabric.
