Continuous Feeding vs. Intervals

Swing type sealing uses multiple servo units to synchronize movement of the rollers in the opposite direction of the film feed. This manoeuvre isolates the film feed during sealing period while Infeed & outfeed remain in motion (in oppose to intervals). The sealing is also tensionless therefore avoid weld line elongation for thick film.

This mechanism is ideal for thick bag production with long feeding length. It also speeds up all the
bag on roll products production by triple times.

Benefits:

Non-stop infeeding & outfeeding during sealing time highspeed production @ 120-150M/min
Tensionless sealing for thick bag
Avoid elongation of weld line for large bag & thick bag
Precise sealing time can be set by PLC

Interleaved Winder

Interleaved winder unit could produce interleaved drawtape bag or interleaved flat bag at 120M/min.

Interleaved products for house hold garbage packaging bags are becoming increasingly popular for its convenience as consumers no longer need to tear off the bag by the perforation line. This novelty provides high added value to the garbage bag and a favorable trend demanded by the world's leading brand owners.

Plas Alliance here presents interleaved winder and it is applicable to following bag types:

Flat garbage bags
C-folded garbage bags
Starseal garbage bags
S-shape garbage bags
Drawtape garbage bags

Drawtape Garbage Bag Procedures and Accessories

1. Double triangle folding device

Folding finished bag vertically prior to rewinding or horizontal folding

2. Main machine

Servo motor - Accuracy and highspeed @65M/min
Malfunction alarm / stop - Abnormal temperature / No material feed / Photocell track miss / Bag jam
Upgradeable to Swing-type sealing unit - Using servo-synchornized counter movement to the film flow, swing type sealing unit can seal without intervals on the film flow securing strong welding results and increase productivity.
Optional Rotary type perforation device

3. Horinzontal lip sealing

For lip folding seal, multiple types of sealing are available
Continuous hot air type
Continuous heat-wire type
Up-down sealing type
Servo-driven up-down sealing type

4. Automatic splice unit

Dual motor - Driven bobbin feed auto-splices without stopping machine

5. Servo-driven semi-circular hole punch + Air-release notch

Servo driven punch provides high reaction speed for high-speed production

6. Edge position control guide unit

7. Unwinder System

High-speed heavy-duty unwinder set
Pneumatic lift arm - Allow operator to change heavy film alone and avoid occupational harm
Pressor Roller - Motor driven pressor roller helps to unwind film smoothly during high-speed production

S-shape Garbage Bag Procedures and Accessories

Rotary Die cutter

Servo driven rotary die cutter can be accomodate the highspeed production of swing type sealing with quick response and length/position adjustment by synchronizing the film feed and rotary activation.

Cutter blade strip is attached to the rotary cylinder by magnetic for easy change and disposal.

Heat-slitting & Post-gusset System

Heat-slitting - Heated slitting blade will slit and seal the edge of the passing film.
Post-gusset - Heat-slitted tubic films are blown up again and form gusset on the wooden gusset device similar to blown film machines.
