Who are our partners

Trusted by OEM factories for consistent, clean, and secure sealing results. Our equipment is designed to handle multiple carton sizes, heavy loads, and long-distance transportation demands without compromise.

Our featured carton sealers

We deliver sealing equipment built around your exact carton dimensions, packaging speed, and operational requirements.

One-Touch Automatic Carton Sealer

The one-touch automatic carton sealer uses dual side-belt drives to apply top and bottom tape, ensuring fast, smooth and neatly aligned sealing performance. The width and height can be manually adjusted to fit different carton sizes. It is widely used in packaging lines for food, pharmaceuticals, toys, tobacco, personal care products and electronics.

Side-Sealing Carton Sealer (Top & Bottom Drive)

This side-driven carton sealer applies tape to the top and bottom of the carton using belt-driven transmission. It is ideal for wide, heavy or unevenly loaded cartons, offering stable sealing without skewing. Commonly used for electrical appliances, household electronics and large outer cartons.

Fully Automatic Corner Sealer (Four-Edge Sealing)

The fully automatic corner sealer reinforces the four corners of the carton after top and bottom sealing, creating a stronger packaging structure for transportation. It is suitable for export shipments, heavy industrial goods and high-value products, effectively reducing damage during stacking, warehousing and long-distance transit.

Automatic Flap Folding & Tape Sealing Machine

Unlike standard carton sealers, this model automatically folds the flaps and then applies tape, achieving a fully automated sealing process with minimal manual intervention. It can be integrated with case erectors, conveyors and strapping machines to form an efficient packaging line. Ideal for e-commerce warehouses, OEM contract packing, fast sorting operations and high-volume consumer goods packaging.

Automatic Flap Folding Carton Sealer (Hot Melt Glue)

This version provides higher sealing integrity (including optional hot-melt sealing solutions) based on automatic flap folding. It is suitable for corrugated cartons requiring stronger bonding, moisture resistance and tear-proof sealing. Commonly used for export packages, cold-chain logistics, chemical products and precision instruments.

Side + Top & Bottom Drive Carton Sealer

This carton sealer features a four-belt drive system that supports both top and bottom sealing, with manual adjustment for different carton widths. It offers flexible application across multiple carton sizes and packaging needs. Suitable for packaging plants, third-party warehouses, small appliances, personal care products, electronics and export packing lines.

Seal smarter, pack faster

From mixed carton sizes to high labor costs and transit damage, we solve the most common packaging challenges with industrial-grade sealing automation.

Handle different carton sizes easily

Stop slowing down your packaging line whenever carton sizes change. Our sealing machines allow quick width and height adjustments to fit multiple carton specifications without downtime. Whether you’re packing fixed-size products or mixed SKUs, you can keep production moving fast and consistently.

Cut labor costs and boost sealing efficiency

Manual taping takes time, causes fatigue, and leads to inconsistent results. With automated flap folding and sealing, one operator can manage multiple machines while maintaining a steady production pace. Reduce repetitive labor, control packaging costs, and improve overall throughput in your facility.

Stronger sealing to prevent carton opening

Uneven tape, loose flaps, or weak pressure can lead to cartons bursting open during shipping and handling. Our sealing solutions ensure tight, uniform tape application, including corner reinforcement for extra protection, so every carton stays secure through warehousing, express delivery and ocean freight.

Which type of carton sealing machine is right for you

Choosing the right sealer depends on your carton size, daily volume, and packaging workflow. Answer a few simple questions to find the best solution for your operation. No technical knowledge required.

1. Are my carton sizes consistent every day?

✔ Yes → You need a uniform size carton sealer, top & bottom sealing.

✗ No (mixed sizes, multiple SKUs daily) → You need an automatic adjustment / auto flap-folding carton sealer.

2. Are my cartons wide, heavy, or unevenly loaded?

✔ Yes → You need a side-driven carton sealer, side belt / top & bottom drive.

✗ No, mostly standard lightweight cartons → You need a standard top-and-bottom drive carton sealer.

3. Do my products require export shipping or pallet stacking?

✔ Yes → You need a fully automatic corner carton sealer, I-seal + four-corner sealing.

✗ No, mainly domestic shipment → You need a top & bottom sealing machine with auto flap-folding.

4. Do I need stronger sealing for heavy or high-value products?

✔ Yes → You need a corner sealing machine (four-corner reinforcement).

✗ No, general fast-moving consumer goods → You need a standard tape sealing machine, top & bottom.

5. How many packing operators do I have?

✔ Two or more operators dedicated to sealing → You can start with a uniform size carton sealer.

✔ I want one person to operate 2–3 machines → You need an auto flap-folding or automated packaging line.

6. How many cartons do I need to seal per day?

✔ Low volume: 100–300 cartons/day → Choose a semi-automatic carton sealer.

✔ Medium volume: 300–800 cartons/day → Choose a uniform size or side-driven carton sealer.

✔ High volume: 800+ cartons/day → Choose an auto flap-folding / fully automated carton sealing line.

Packaging requirement	Recommended machine
Uniform carton sizes, 200–400 cartons/day	Uniform size carton sealer (top & bottom sealing)
Wide or heavy cartons	Side-driven carton sealer
Export shipping, pallet stacking, high-value goods	Fully automatic corner carton sealer
Multiple carton sizes, high order volume	Automatic flap-folding carton sealer

Carton Packaging Line Solutions

Whether you’re sealing a few hundred cartons a day or managing high-volume, multi-shift production, our modular packaging lines help reduce labor, improve consistency, and protect your goods in transit.

Entry Level Carton Packaging Line

This basic packaging solution covers the essential processes from carton forming and sealing to corner reinforcement. It is designed for companies transitioning from manual packing to semi-automation. Ideal for low-to-medium daily output, product repacking, or warehouse shipment scenarios

Middle Level Carton Packaging Line

The mid-range solution introduces automatic flap folding, top and bottom taping, and optional four-corner sealing in a single continuous flow. It supports multiple carton sizes and can integrate with conveyors, labeling, or strapping systems to boost packaging speed. This layout is well-suited for multi-SKU production lines, e-commerce fulfillment operations.

High Level Carton Packaging Line

This advanced packaging line delivers end-to-end automation, from carton erecting and sealing to corner reinforcement, strapping, and robotic handling. It supports high-capacity production, standardized packaging requirements, and export-grade load protection for palletizing and long-distance transportation.

Our areas of expertise

Electronics

Sensitive products demand secure, reliable packaging to avoid impact or humidity damage.

Food & Beverage Packaging

High throughput and repetitive sealing tasks increase labor cost and reduce productivity.

Overseas Container Loading

Stacked pallets and ocean freight create pressure that can easily break weak seals.

E-commerce Warehouses

Frequent SKU changes and mixed carton sizes slow down manual packing and create sealing inconsistencies.

Home Appliances

Heavy cartons and long-distance transport require stronger protection and consistent sealing quality.

Chemicals & Industrial Manufacturing

Boxes used for chemicals or hardware need stronger adhesion and leak-proof sealing.
