المشاكل والحلول

إجابات عملية على التحديات الشائعة في مواد البلاستيك

LDPE Film Lamination Delamination

Material Drying LDPE; film; lamination; delamination; peeling; adhesive

Poor Printing Adhesion of LDPE Film

Printing adhesion = dyne value + aging.

Extrusion & Post LDPE; film; printing; corona; dyne value

LDPE Film Static Electricity Problem

Static electricity = the three-piece set of eliminator + humidity + grounding.

Material Drying LDPE; film; static electricity; antistatic; ambient humidity

LDPE '2079851475616104452 Sink Marks

Sink mark = compensation problem.

Injection Molding LDPE; '2079851475616104452; sink mark; holding pressure; thick wall

LDPE '2079851475616104452 Mold Sticking

Injection Molding LDPE; '2079851475616104452; warpage; shrinkage; cooling

LDPE Extrusion Coating Pinholes

Pinhole = check three: film rupture + substrate contamination + thin layer.

Extrusion & Post LDPE; extrusion coating; pinhole; coating; substrate

LDPE Extrusion Coating Neck-in

Extrusion & Post LDPE; extrusion coating; neck-in; Neck-in; air gap

Uneven Tightness of LDPE Film Rolls

Eighty percent of film roll problems come from the film's own thickness.

Extrusion & Post LDPE; film; film roll; tension taper; winding
