What materials can be packaged using this machine?
These machines are highly versatile and compatible with a wide range of laminated films, including PET/AL/PE, PET/PE, Paper/PE, and Nylon/PE. They are commonly used for packaging food sauces, cosmetics, pharmaceutical powders, and chemical liquids.
What are the benefits of 4-side seal packaging?
Four-side sealing offers superior package aesthetics, high structural strength, excellent barrier protection against moisture and oxygen, and a flat, neat layout that allows maximum surface area for branding and product information.
Can the sachet size and filling volume be adjusted?
Yes, sachet dimensions (length and width) and filling volumes can be adjusted. Depending on the machine model, adjustments can be made via the PLC touch screen interface, changing the forming shoulder, or configuring the dosing pump/auger system.
How does the machine maintain filling accuracy?
The machine utilizes high-precision dosing devices such as piston pumps for liquids/pastes, volumetric cups for free-flowing granules, or auger fillers for fine powders, ensuring consistent fill weights and minimal product waste.
