Gravy Soup Fruit Juice Multifunctional Packaging Machine 304/316 Stainless Steel Contact Surface Anti-oxidation / Rust

For the packaging needs of gravy (liquid or paste), a special packaging machine should be selected according to the product characteristics (viscosity, temperature, anti-corrosion requirements) and production capacity targets.

1. Core elements of gravy packaging machine selection

Classification by process

Liquid filling machine: suitable for low-viscosity gravy (such as clear soup), using gravity/pressure filling.

Paste filling machine: suitable for high-viscosity gravy (such as thick soup sauce), requires a screw pump or piston pump.

Vacuum packaging machine: when the shelf life needs to be extended, vacuum and seal (such as aluminum foil bag packaging)

2. Key points for selecting prefabricated bag packaging machine

Equipment type

Bag-feeding automatic packaging machine: specially designed for prefabricated bags, automatically completes bag opening, filling and sealing.

Applicable bag types: three-side sealed bags, self-supporting bags, zipper bags, special-shaped bags (customized clamps are required).

Key functional modules

Automatic bag picking: vacuum suction cups or mechanical grippers accurately grab prefabricated bags.

Bag support mechanism: air pressure or mechanical fingers support the bag opening to facilitate manual/automatic feeding.

Heat sealing device: constant temperature controlled sealing (applicable to common prefabricated bag materials such as PE and CPP).

3. Recommendations for selecting prefabricated bag materials

Common structures

Transparent bags: PET/PE (suitable for displaying products, low cost, general barrier properties).

Aluminum foil bags: PET/AL/CPP (high barrier, light-proof, and extend the shelf life of gravy and soup).

Stand-up bag: bottom reinforcement design for easy retail display.

Sealing compatibility test

The matching of the inner material of the prefabricated bag (such as CPP) with the heat sealing temperature needs to be tested in advance to avoid cracking or leakage of the seal.
