Technical guide visual for Why Same Price Packaging Bags Can Have Different Quality.Learn why packaging bags with the same price may have different quality. Material structure, thickness, printing, lamination and hidden costs explained.
Краткий ответ
Many buyers compare suppliers by unit price. But the same price does not always mean the same product.
Same Material, Different Structure
PET/PE, PET/VMPET/PE and PET/AL/PE are starting points. Thickness, raw material grade, sealing layer and barrier performance can differ significantly between suppliers.
Thickness Matters
Film thickness affects cost, stiffness, sealing and puncture resistance. The right thickness depends on product, filling weight and usage. Not always thicker is better.
Printing Beyond Colors
Registration, color consistency, ink adhesion, text sharpness, surface finish and artwork checking all affect the final printed result.
Lamination and Curing
Bond strength, solvent residue, curing time and appearance after lamination affect long-term stability and food safety.
Sealing and Tolerance
Sealing strength, pouch dimension tolerance, zipper position, spout welding, gusset folding and roll film slitting accuracy matter for machine users.
