A Back Sealing Packaging Machine is an automatic packing system that forms, fills and seals packages with the seal located on the back of the pouch. This model uses microcomputer control and optical technology for accurate, high-speed packaging — particularly suited for tea and other small-packet products.
It can handle powders and granules (for example tea leaves, seasoning powder), cereals, dried nuts, hardware accessories, and small electronic components, provided the product flow characteristics are compatible with the chosen feeding system.
Basic steps are: install the roll film, connect power and start the control system, set your packaging parameters (length, sealing temperature, speed), load product into the hopper or feeding system, then start production. The machine will form the pouch from roll film, dose product, and perform back sealing.
It typically accepts heat-sealable roll films such as laminated PET/PE, OPP/PE and other multi-layer films suitable for back-seal pouches. Film compatibility depends on heat-seal properties and film thickness — check with the supplier for supported film specifications.
Speed depends on product type, pouch size and model configuration. Typical speeds range from a few dozen to several hundred pouches per minute. Ask the supplier for speed charts based on your product and pouch dimensions.
The machine uses microcomputer control and optical technology for high positioning accuracy and consistent sealing. Dosing accuracy will depend on the chosen filler (auger, cup, volumetric, or multi-head weigher) and product properties; consult the supplier to match the proper dosing system to your product.
Power requirements vary by model and optional equipment. Common industrial machines use three-phase power (e.g., 220–380V, 50/60Hz). Confirm exact voltage, phase and power consumption with the manufacturer or your local sales representative.
Roll film installation is designed to be straightforward: mount the roll, thread the film through the film path and alignment guides, and set the registration with the optical sensor. The microcomputer control typically offers menus to input pouch length and other parameters. Training is recommended for efficient changeovers.
Regular maintenance includes cleaning the sealing jaws and product contact areas, checking and replacing worn seals and cutter blades, lubricating moving parts per the manual, inspecting sensors and electrical connections, and verifying temperature control. Follow the manufacturer's maintenance schedule.
Disconnect power and follow lockout procedures, then remove product-contact parts if detachable. Wipe down surfaces with food-safe cleaners, avoid water contact with electrical components, and ensure all parts are dry before restarting. Refer to the supplier's cleaning instructions for model-specific guidance.
Typical safety features include emergency stop buttons, safety guards or interlocks around moving parts, thermal protection for heaters, and electrical overload protection. Exact features vary by model; review safety documentation before operation and ensure operators are trained.
Yes. Common options include different dosing systems (auger, volumetric cup, multi-head weigher), nitrogen flushing, date/lot coders, pouch window or zipper attachments, and upgraded control packages. Contact the manufacturer to discuss optional configurations suited to your application.
Check film compatibility and sealing temperature, ensure sealing jaws are clean and undamaged, verify correct pressure and dwell time, confirm film alignment and registration, and inspect the cutter blade if present. If problems persist, consult the manual or supplier support.
Lead times depend on model, customization and order volume; small standard machines can often ship in weeks, while custom systems take longer. Warranty and after-sales support vary by supplier — confirm warranty length, spare parts availability and service options before purchase.
It can benefit both. For tea shops, a compact model automates packaging and saves labor. For larger producers, higher-capacity configurations and integrated dosing systems increase throughput. Choose machine size and options according to your production volume and budget.
