B2B Buyer Guide & FAQs
Answers to common questions about selecting, customizing, and operating liquid sachet packaging machinery.
Q1: How do you ensure filling accuracy for liquids of varying viscosities?
We configure each machine with dosing systems tailored to the product’s viscosity. For free-flowing liquids (like vinegar or oils), we utilize high-precision rotary valves or flow meters. For highly viscous pastes (like ketchup or facial scrubs), we employ servo-driven piston pumps. This ensures a consistent filling accuracy of ±0.5% to ±1%.
Q2: Can a single multi-lane machine handle different sachet sizes?
Yes, sachet length can be adjusted directly via the PLC touchscreen. However, changing the sachet width requires changing the forming tube and sealing jaw assembly. Our machines feature a modular design that allows for quick changeovers, minimizing downtime.
Q3: What types of packaging film materials are compatible with your machines?
Our sachet packaging systems work with a wide range of heat-sealable laminated films, including PET/AL/PE, PET/PE, Paper/PE, and NY/AL/PE. We also offer options for eco-friendly, recyclable, and biodegradable films.
Q4: How do you prevent product leakage and ensure seal integrity?
We use advanced PID temperature controllers to maintain consistent heat across the sealing jaws. In addition, pneumatic anti-drip nozzles prevent liquid from contaminating the sealing area, ensuring a reliable, leak-proof seal.
Q5: What is the typical lead time for a customized liquid sachet packaging line?
Standard models are typically delivered within 30 to 45 days. Customized systems or fully integrated turnkey production lines may require 60 to 75 days, depending on the complexity and scope of the engineering work.
