Direct-Heating Sealing Machine – Product Description

The pneumatic direct-heat sealing machine is equipped with Teflon-coated heating jaws on both the upper and lower sides, controlled by a PC board. It requires 7–10 minutes of preheating and must maintain the set temperature during operation.

The Teflon heating jaws are available in two patterns—cross-hatch and horizontal—both with a width of 10 mm.

To operate, hold the packaging bag with both hands and lightly step on the foot switch. When the sealing indicator light turns off, heating stops. Continue pressing for 3–6 seconds to allow proper cooling and the sealing is completed.

Suitable sealing materials include flat aluminum foil bags, nylon bags, and sterilization bags.

Applicable industries: food, electronics, hardware components, chemical products, agricultural products, coffee industry, medical supplies, and more.

The machine features a steel-plate body with powder-coated finish, offering simple operation, safety, and long-lasting durability.

Horizontal band sealer

The horizontal continuous sealing machine features a clean and simple exterior, with a durable powder-coated finish (optional full stainless-steel construction available). Equipped with comprehensive functions, it completes sealing in one smooth process, ensuring products reach a fully sealed state.

The machine body can be tilted forward 0–15 degrees to suit operator preferences. An optional printing unit (ink-roller type or ribbon-type coder) allows users to print manufacturing dates and batch numbers, enabling sealing and printing to be completed in a single operation—eliminating the need for secondary processing.

This machine is suitable for food products, hardware parts, electronic components, and more, offering simultaneous heat sealing and printing.

Applicable Materials: Aluminum foil bags, nylon bags, coffee bags, and various other heat-sealable packaging materials.

Vwrtical band sealerr

The vertical continuous band sealer is suitable for mass production and ideal for sealing packaging that contains liquid products.

It allows temperature adjustment according to different packaging materials (such as PE, PP, aluminum foil bags, and laminated bags) and can be paired with adjustable conveyor speed to ensure smooth, consistent sealing quality.

The vertical continuous band sealer is suitable for packaging powder, liquid, and granular products.

It is widely used for sealing various hardware items, liquids, powders, granules, pastes, and oily substances.

Foot type constant heat sealer

The foot-operated impulse sealer is a single-line impulse sealing machine equipped with electronic timing control. Its impulse heating method requires no preheating, but does require a brief pressing and cooling period.

Place the bag on the sealing area, step on the pedal, and wait 2–3 seconds after the indicator light on the controller turns off to complete the seal.

The single-line seal is suitable for PE plastic bags.

The machine features a powder-coated steel body, offering simple operation, safety, and long-lasting durability.

Compatible sealing materials include PE, PP, OPP, PVC, and POF.

It is suitable for a wide range of industries such as food, hardware, chemicals, agriculture, coffee, medical supplies, and many others.

Auto impulse sealer

Automatic Impulse Sealer – Product Description (English Version)

The automatic impulse sealer requires no preheating; it is ready to seal immediately upon startup.

The machine is equipped with an electromagnetic control system and an electronic timer, allowing the sealing, pressing, and cooling processes to be completed in one cycle. This design effectively prevents issues such as uneven sealing caused by manual operation.

The entire machine features a durable powder-coated finish and can also be customized with a stainless-steel body (SUS 304).

Multiple seal lengths are available to meet different packaging requirements.

Applicable Materials: PE, PP, OPP, PVC, POF, thin nylon, thin aluminum foil, and other heat-sealable materials.

Suitable Industries: Food processing, electronic components, chemical products, hardware parts, and more.

Hand pressure sealing machine

The hand sealer is one of the simplest sealing machines to operate, ideal for various light-duty packaging applications.

Place the bag opening flat on the sealing line and press down the handle to complete the seal.

Compact and space-saving, it requires no preheating—ready to use immediately.

An optional 0.6 mm cutting seal wire is available to trim off excess bag material during sealing.

The machine body is made of steel with a durable powder-coated finish for long-lasting use.

Multiple sealing lengths are available (200 mm to 400 mm).

Suitable for common film materials such as PE, PP, OPP, PVC, and POF.

The hand sealer is the perfect sealing choice for small-volume production and DIY packaging.

AIR-suction sealerr

Vacuum-Type Sealing Machine – Product Description (English Version)

The vacuum-type sealing machine features a clean and simple exterior, constructed with a durable powder-coated finish (optional full stainless-steel construction available).
With its comprehensive functionality, the machine completes vacuuming (vacuum motor optional: vacuum pump or blower) and sealing in one smooth process. This minimizes contact between the product and air, significantly increasing storage and packing efficiency.

The machine body can be tilted 0–15 degrees forward, allowing operators to adjust according to their working habits. An optional printing unit ( ink-roller type or ribbon type ) enables printing of manufacturing dates and batch codes, allowing vacuuming, sealing, and printing to be completed in a single operation, eliminating the need for secondary processing.

This vacuum-type sealing machine is ideal for food products, hardware parts, electronic components, and more. Simply place the bag on the conveyor; the external stainless-steel suction nozzle removes the air, followed by heat sealing + printing, all completed in one step.
