Advantages	RYMACH	Others
1. Operate Panel	Equipped with PLC + color touch screen, easy to operate and adjust parameters.	Normal button + simple temperature control panel.
2. Sealing Cutter	Teflon coating + alloy steel frame, high temperature resistance without deformation.	Ordinary coating or no coating, prone to the mucous membrane and deformation after long-term use.
3. Shrink Tunnel	Chain conveyor + global hot air, no wrinkles, no bubbles, and the finished product is transparent; Equipped with a visual window, can observe the situation of the shrink tunnel in real time.	The mesh belt conveyor is prone to deviation, uneven local shrinkage, and many wrinkles and bubbles. And without a visual window.
4. Temperature Controller	Omron temperature controller, independent temperature control, constant temperature sealing and cutting, non-stick knife, non-burnt edge.	The domestic ordinary temperature control meter, the sealing knife is prone to sticking and yellowing.
6. After-Sale Service	1 year warranty, lifetime maintenance; Online technical training+remote diagnosis; Attached product introduction.	Only a 1-year warranty, some do not provide after-sales service.

Product Overview

Single or group packaging of tableware, wallpaper roll, tube, paper roll, paper boxes, jumbo roll, food container, cosmetics, skin care products, spray cans, medical supplies, filter, appliances, boxes, paper trays, paper cups, and other products.

PLC touch screen control, operation can be done on the screen, the machine has high production efficiency, and is easy to use.

Side sealing knife can be sealed continuously, the product packaging length is infinite, and the height of the side sealing knife can be adjusted by hand wheel.

An optional color film positioning function is available.

Infeed conveyor and output conveyor are available according to product needs.

The heat shrink tunnel has a visible window through which the product shrinkage can be observed in the furnace at any time.

The hot air circulation shrinkage tunnel makes the product's shrinkage effect flat and beautiful.

Product application?

Ideal for small regular goods: medicine boxes, cosmetic packs, filters, switches, small toys & grouped items.

Running speed & production capacity?

Standard 15-30 packs/min

Compatible shrink film?

POF center folded shrink film (15-30μm) as primary option.

Total power & customizable export voltage?

Total power 13.5KW, standard sealing machine is 220V,1 phase, shrink tunnel is 380V, 3 phase; custom 220V/415V available, CE certificate for customs clearance.

Free sample test & customization lead time?

Free sample wrapping test in the factory; minor modification:7 working days, in-stock machine delivery within 1~3 days.

Compressed air required for the machine?

Clean compressed air (0.5MPa) needed.

Film bulges with trapped air after shrinking?

1. Add a pin roller for exhaust holes.
2. Reduce conveyor feeding speed.
3. Raise front tunnel temperature for full air exhaust.

Wrinkled loose wrapping film?

Low tunnel temp / over-fast feeding → increase temp or slow down; uneven film tension → adjust roller spring; oversized film → switch to a narrower POF roll.

Film runs off track & uneven side sealing edge?

Fix film roll centrally; balance left-right roller tension; straighten feeding limiting fence; recalibrate photo eye position & sensitivity.

Seal splits/burnt or cutter sticks to film?

Split seal: raise cutter temp & cylinder air pressure; Burnt seal: lower temp or speed up machine; Sticky cutter: replace worn Teflon anti-stick tape.

Cutter scratches the product accidentally?

Modify servo cutter stroke on HMI; realign feeding baffle; fine-tune cutter lifting height screw.

Partial tunnel, no heating / unstable temperature?

Replace broken heating tube; fix loose thermocouple or defective solid-state relay.

Sealing mechanism stuck with abnormal noise?

Clean film scraps on the chain/rail; add high-temperature grease; drain water from the air filter.

Film cracks after thermal shrinking?

Reduce overheat of the relevant tunnel zone; change the qualified POF film; add edge protection for sharp products.

Regular maintenance checklist?

Daily: Clean cutter residue & conveyor scraps, wipe photo sensor lens.
Weekly: Lubricate chains & guide rails, drain water from air filter.
Monthly: Tighten all bolts, clear carbon dust inside the tunnel, and inspect the blower & motor.
