Envasado flexible para caramelos, chocolate y galletas
Tipos de Envasado Recomendados
- Food packaging roll film (laminated roll film for VFFS/HFFS automatic packing), three side seal pouch (single-serve candy or biscuit sachets), stand-up zipper pouches (resealable format for retail candy and cookie packs), custom shaped pouches (die-cut shapes for specialty candy or gift packaging). Candy and biscuit packaging often needs moisture barrier, stable sealing, accurate printing and good compatibility with automatic packing machines.
- BOPP/CPP (most common for biscuit and candy flow pack; good machinability and transparency), PET/PE (stronger sealing for heavier cookie packs), PET/VMPET/PE (improved moisture and light barrier for premium confectionery), cold seal film (no-heat sealing for heat-sensitive chocolate). Final structure confirmed based on product type, oil content, shelf life, packing machine type and speed.
- Each batch undergoes eye mark accuracy check, COF (coefficient of friction) measurement, sealing temperature window verification, film tension stability test, roll width tolerance check, print registration inspection and visual appearance inspection. Sample testing with actual packing machine recommended before bulk production.
- Product type (candy/biscuit/chocolate), packing machine brand and model, roll width and repeat length, film structure preference, sealing type (heat seal/cold seal), barrier requirements (moisture/oxygen/light), printing colors and artwork file, estimated order quantity, target shelf life, destination country or region.
- Food Packaging Roll Film, Three Side Seal Pouch, Stand Up Zipper Pouches, Custom Shaped Pouches.
- Q: Should biscuit packaging use roll film or premade pouch? A: Roll film is commonly used for automatic flow pack lines. Premade pouches are suitable for retail, gift or resealable packs. Q: Can cold seal film be used for all candy products? A: Cold seal film is commonly used for heat-sensitive chocolate. The final structure should still provide appropriate barrier and sealing strength for the product. Q: What causes biscuit moisture absorption in packaging? A: Insufficient moisture barrier, poor seal integrity or film damage may lead to moisture ingress. PET/VMPET/PE structures can help improve moisture protection.
Sugerencias de Materiales
Material recommendations by product type: dry products typically use PET/PE or BOPP/CPP; oily or high-aroma products benefit from PET/VMPET/PE or PET/AL/PE for better barrier; liquids and sauces need NY/PE or PET/AL/PE for chemical resistance and leak-proof sealing; frozen products use cold-resistant PE layer; high-temperature sterilization uses PET/AL/CPP or PET/AL/PA/CPP retort-grade structures. Huasheng Packaging recommends suitable structures based on specific product type and shelf life requirements.
Puntos de Control de Calidad
Each batch undergoes: print color consistency check, lamination bond strength test, heat seal strength test, dimensional tolerance measurement, visual inspection. Application-specific: puncture resistance, chemical resistance, moisture barrier, cold impact resistance, seal integrity (leak/burst). Pre-shipment inspection with retained samples.

Problemas Comunes
- Galletas que se ablandan por la humedad — confirme la barrera contra la humedad en la estructura de la película
- Caramelos que se pegan o se ven afectados por el calor — verifique la resistencia al calor del material
- El tamaño del paquete no coincide con el peso de llenado — confirme las dimensiones y el volumen
- Sellado térmico inestable — verifique la temperatura de sellado y la compatibilidad del material
- Desajuste de velocidad de la película en rollo con la máquina — confirme el COF y los parámetros
Puntos de Control de Calidad
- Prueba de resistencia del sellado térmico
- Precisión de la posición de la marca de ojo
- Control de tensión y planitud de la película en rollo
- Verificación de la barrera del material
- Inspección de apariencia y color de impresión
Preguntas Frecuentes
¿Qué material es adecuado para el envasado de caramelos y galletas?
BOPP/CPP es común para el envoltorio flow pack de caramelos ligeros. PET/VMPET/PE proporciona barrera contra la humedad para galletas. La estructura debe coincidir con el tipo de producto y los requisitos de vida útil.
Can the roll film run on automatic packaging machines?
Yes, we can produce roll film compatible with most flow wrap and VFFS machines. Roll width, core size, eye mark and COF should be confirmed.
How can I prevent biscuits from absorbing moisture?
Use PET/VMPET/PE or PET/AL/PE barrier structures, confirm sealing integrity, and include desiccant if needed. Storage conditions should also be reviewed.
Can you support multi-flavor or multi-SKU packaging?
Yes, for medium and large gravure printing orders, multi-SKU artwork planning and coordinated production scheduling can be supported.
¿Qué debo preparar antes de solicitar una cotización?
