Import Dl-D Series Hot Seal And Cool Cut Bottom Sealing — Buy in Bulk from Supplier in China

The Dl-d series machine produces heat-sealed and cold-cut bottom-sealed plastic bags, including flat-end and optional t-shirt styles. It operates with a servo motor system for precise material conveyance and a Panasonic photoelectric sensor system that detects color changes with high sensitivity, ensuring accurate bag length control. The computerized control panel allows users to set bag length up to 1300mm, production speed between 30 and 150 pieces per minute, and adjusts sealing temperature dynamically based on film thickness.

The machine handles film thicknesses from 0.02mm to 0.20mm, compatible with common polyethylene and polypropylene films used in retail packaging. The sealing and cutting mechanism is designed for consistent performance across varying film densities, reducing waste from mis-seals. The system’s cooling blade ensures clean cuts without melting the film edge, a feature critical for maintaining bag integrity in high-volume operations. Standard industrial components are used throughout, with no proprietary or unverified subsystems reported.

This equipment is typically purchased by small to mid-sized packaging manufacturers in Asia and Latin America who produce branded retail bags, grocery sacks, or promotional pouches. Buyers commonly require delivery on seaworthy wooden pallets, with machine dimensions of 3.0m x 1.76m x 1.5m. The total power draw is 2.7kW. Buyers should confirm packaging type, voltage compatibility, and after-sales support availability before ordering, as no warranty or service terms are stated in the listing.
