Core Functions

A few working parts define how the Model 800 Heat Seal Cold Cut Bag Making Machine runs day to day.

Film feeding relies on a stepping motor paired with photoelectric tracking, which keeps bag length consistent and the film aligned as it moves through the machine — this matters most when film has printed color marks that need to line up with each cut.

Sealing and cutting are handled together through a heat-seal, cold-cut process. The bag mouth is sealed with heat first, then cut once it's cooled, which is what keeps the seal edge flat instead of warped from cutting hot film.

A computer control panel manages counting and can be set to trigger an alarm once a target bag count is reached, so operators don't need to track output manually during a run.

Speed is adjusted through a frequency converter on the main motor, giving some flexibility to slow down or speed up depending on film thickness or bag size.

The machine can also be paired with a separate punching machine for buyers who need handle holes cut into finished bags.

Procurement Motivations

Launching a private label bag line — smaller packaging businesses use a single-channel machine like this one as an entry point into producing their own bags in-house, rather than sourcing from a third-party bag supplier.

Supplying wholesale retail packaging — distributors who need a steady, dependable output of standard flat and vest bags find a single-lane setup easier to manage and less demanding on maintenance than a multi-lane line.

Keeping production costs controlled — a single-channel machine has a smaller footprint, lower power draw, and simpler operation than a dual-lane setup, which keeps per-unit costs down for buyers not yet ready to scale to higher output.

OEM/ODM Support

Wenzhou Chaoshun Machinery can adjust configuration on this bag making machine to match specific buyer requirements — including feed motor setup, sealing knife style, and accessory brands. Buyers developing their own bag product line can work directly with the factory to align machine settings with their target bag dimensions and film specifications before the machine ships.

FAQ

Q1: What does "heat seal cold cut" mean for bag quality?
The bag mouth is sealed while heated, then cut once cooled, which keeps the seal edge flat and firm rather than warped.

Q2: Is this a single-lane or multi-lane machine?
Single-channel — one bag is produced per cycle, which suits standard-volume production rather than maximum-output runs.

Q3: Can the configuration be adjusted for specific bag sizes?
Yes, OEM/ODM adjustments are available, including feed motor and sealing setup, based on the buyer's target bag dimensions.
