💡 Note: The 4 process inspections are parallel checkpoints - products go through the relevant processes based on their type. For example: film-only products go through "Raw Material + Film Blowing" inspection and then directly to QC Manager Final Inspection; printed products add "Printing" inspection; bag products add "Bag Making" inspection. Regardless of which processes are involved, all products must pass QC Manager Final Inspection and Pre-shipment Inspection before shipment.

PE heat shrinkable film, for raw material incoming, in-process and final inspection

Low density polyethylene blown film, for raw material incoming, in-process and final inspection

High density polyethylene blown film, for raw material incoming, in-process and final inspection

Gravure printing on plastic film, for PE shrink film, LDPE, HDPE printing process

Film slitting, folding, gusseting, edge sealing process inspection

Plastic bag heat sealing, cutting, forming process inspection

Batch Definition

Same raw material, same process, same spec continuous production = one batch. Film ≤40 rolls/batch, bags ≤20,000 pcs/batch

Sampling Rules

First article mandatory inspection. Film: at least 1 check per 10 rolls. Printing/bag making: patrol every 30 min. First article signed by operator + QC

Final Inspection

Width tolerance, thickness, grammage, appearance = mandatory per batch. Other items per customer request or at least once per week sampling

Type Inspection

Full item inspection for: new product launch, major raw material/process change, every 6 months normal production, resuming after 6+ months shutdown

Judgment Rules

All items pass = batch qualified. Failed items: double sampling re-test. Still fails = batch unqualified, handled per Nonconforming Product Control Procedure

Thickness Gauge

0.001mm precision, measures film thickness uniformity

Tensile Tester

Tests tensile strength, elongation at break, tear strength

Seal Tester

Tests bag seal strength, sealing performance, leakage rate

Heat Shrinkage Tester

Tests MD/TD shrinkage rate and shrink temperature of films

Haze Meter

Measures film transparency, haze, and glossiness

Friction Coefficient Tester

Measures film surface friction coefficient for smooth machine feeding

Temperature Resistance Tester

Tests high/low temperature resistance for different applications

Print Quality Inspector

Online inspection of print registration, color difference, defects
