APR recognizes that innovators are faced with a large number of possible issues that new packaging may impact. The links at the left provide specific questions to consider for specific categories of innovation.
Effect of bottle manufacture/appearance/performance
Effect of staple fiber manufacture/appearance/ performance
Effect of sheet, film & pipe (HDPE) manufacture/appearance/performance,
Effect on engineering resins manufacture/performance,
Effect of strapping manufacture (including solid stating) or appearance or performance
Effect on depolymerization efficiency or quality.
Specific issues
Where on the bottle will the layer/coating be?
Do layers readily delaminate and then separate from HDPE or PET?
Effect on grinding efficiency?
Effect of barrier material on increased flake loss in elutriation?
Effect of residual barrier material (how much to cause an effect) on
Color in melted resin
Haze and black specks for PET, black specks in HDPE
ESC for HDPE
Melting point
Crystallization temperature and rate for PET
Fuming during extrusion
Excessive filter blinding and screen pack life
Bottle making for PET and HDPE (extrusion, viscosity, reheat, melt strength)
Spinning, drafting, and dyeing for PET. Also tenacity, shrinkage, and fluorescence
Sheet making for PET and HDPE (color, gels, impact strength changes, tear strength, tensile modulus, pin holes, black speck occurrence, surface defects)
Solid stating rate for PET
Tensile, flexural, and impact properties for HDPE and PET
6. Food contact compliance
7. Deposits and plate out on dies, pins, and molds
