Preguntas Frecuentes
What does food grade flexible packaging mean?
Food grade flexible packaging means the materials, production process and finished packaging meet requirements for direct food contact. This includes using approved food contact materials, following good manufacturing practices, maintaining a clean production environment, and conducting quality testing throughout production.
What does ISO22000 certification mean for packaging buyers?
ISO22000 is an international food safety management system standard. For packaging buyers, working with an ISO22000 certified supplier like Huasheng Packaging means the factory has established systematic food safety management covering material management, production process control, traceability, hygiene practices and quality documentation — not just final inspection.
What quality checks are important for food packaging bags?
Key checks include material structure confirmation, heat sealing strength, lamination strength, oxygen and moisture barrier testing, dimension tolerance, leakage testing for liquid products, roll film tension and eye mark accuracy for automatic packing, and finished product visual inspection.
How do material structure, oxygen barrier and moisture barrier affect packaging performance?
Material structure determines how well the packaging protects the food. Oxygen barrier (provided by layers like VMPET or aluminum foil) helps prevent oxidation and aroma loss. Moisture barrier (provided by PE or CPP layers) helps prevent the product from absorbing moisture or drying out. The right combination depends on product type, expected shelf life and storage conditions.
What information should buyers provide before quotation?
Buyers should provide product type, filling weight, bag size or roll width, expected shelf life, material structure preference if any, filling equipment type if applicable, quantity, printing colors and artwork file. The more detail you provide, the more accurate the material suggestion and quotation will be.
Can material structure be adjusted for different food products?
Yes. Material structure should be adjusted based on product type, moisture sensitivity, oxygen sensitivity, filling temperature, shelf life requirement and storage conditions. For example, dry snacks may use BOPP/CPP or PET/PE, while coffee needs PET/VMPET/PE or PET/AL/PE for stronger aroma and oxygen barrier.
