Manufacturing Capacity

Our factory utilizes advanced automated production lines and a stringent quality control system to achieve precise manufacturing and stable delivery from raw materials to finished products.
Home / Packaging Industry Transmission Belt Solutions

In the rhythm of packaging production, transmission belts are like a precise heart and pulse—every transmission is crucial for efficiency and stability. Facing the challenges of synchronization at high speeds, the wear and tear from frequent starts and stops, and the durability tests of harsh environments, we offer professional-grade solutions: high-precision synchronous belts ensure zero-slip transmission, wear-resistant reinforced belts handle extreme working conditions, and food-grade PU meets cleanliness and safety requirements. From single-machine optimization to complete line upgrades, we provide reliable transmission solutions to help your packaging production lines operate accurately, resiliently, and sustainably.

Main Belt Types Used in the Packaging Industry

On packaging production lines, the right belt is the cornerstone of efficiency and innovation. From light packaging to heavy-duty strapping, different types of belts act like the "arteries" of the production line, determining the system's speed and reliability. This article will analyze the key belt types and application scenarios in the packaging industry.

Vulcanized Timing Belt

Vulcanized timing belts achieve zero-slip transmission through precise tooth meshing, making them a core component for synchronous conveying and precise positioning in packaging machinery. Their integrated vulcanized high-strength structure is specifically designed for high-speed, heavy-load, and strictly synchronized scenarios, ensuring your packaging process achieves precise rhythm while maintaining stability.

Applicable Scenarios

  • Positioning and pushing of packaging boxes/bags
  • Synchronous transmission systems in filling/sealing processes
  • Rotary cutting and slitting devices

Core Advantages of Vulcanized Synchronous Belts

The core advantage of vulcanized synchronous belts lies in their one-piece precision tooth profile achieving zero-slip powerful transmission, ensuring absolute synchronization and long-term reliability under high-speed operation.

Foam/Sponge Timing Belt

Foam conveyor belts, with their unique combination of an elastic sponge layer and a tough surface, provide cushioning protection and stable transport for your delicate products. Whether it's fragile glass bottles, precision electronic components, or sensitive high-gloss materials, it effectively absorbs vibration, prevents scratches and displacement, achieving a perfect balance of safety and efficiency on packaging lines.

Applicable Scenarios

  • Labeling machine pressure rollers,
  • Label smoothing,
  • Flexible contact areas

Why are Foam Belts Needed?

Foam belts provide irreplaceable cushioning protection for precision and fragile products, acting as gentle guardians for safe transport.

Soft and Safe

Rigid industrial belts can easily cause labels to wrinkle or bottles to scratch.

100% Label Fit

Foam provides elastic cushioning and even pressure, ensuring 100% label fit.

Flat Conveyor Belt

Flat conveyor belts are the lifeblood of packaging lines, each segment bearing the dual responsibility of efficiency and safety. From light-load transport to heavy-load drive, from precision conveying to flexible cushioning—choosing the right conveyor belt is to inject precise and smooth power into your production line.

Material Selection for Flat Conveyor Belts

Choosing the right material is crucial for balancing load-bearing capacity, friction, and durability

PU

Food-grade, wear-resistant, easy to clean (recommended for testing and cooling sections)

PVC

Economical, suitable for carton conveying

Silicone

Excellent high and low temperature resistance (-60°C ~ 250°C), non-toxic and odorless, high friction

Teflon

Super strong anti-stick properties, extremely low coefficient of friction, chemical corrosion resistant, easy to clean

Food-Grade Rubber

Impact resistant, high load-bearing capacity, wear-resistant and slip-resistant, economical and durable

Surface Treatment of Flat Conveyor Belts

Surface treatment is the finishing touch that determines friction, slip resistance, and durability:

  • Flat (General Purpose)
  • Grass/Diamond Texture (Increases friction)
  • Rough/Rusty Surface (Provides gentle gripping force)
  • Guide Strips/Edges (Prevents material deviation)
  • Perforated (Adhesive fixation, ventilation and drainage)
  • Thickened (Cushioning protection, high friction)

Common Pain Points in the Packaging Industry & Belt Solution Strategies

In the packaging industry, common pain points such as jamming, scratches, and slippage constantly constrain efficiency and cost. Carefully selected industrial belts are key to solving these problems—anti-deviation structures ensure stable operation, special surfaces protect products, and synchronous transmission ensures precision. Choosing the right industrial belt precisely addresses production line challenges.
Pain Points & Belt Solutions

Frequent downtime for replacement

Using vulcanized seamless belts, lifespan is increased by 2-3 times.

Performance degradation after cleaning

Using HNBR rubber or PU materials, washable.

Small batch, multi-variety switching

Providing modular stop design for quick replacement.

High-speed tooth slippage/slippage

High-precision tooth profile + reasonable tensioning system.

Food/pharmaceutical compliance risks

Providing FDA and RoHS certified materials.
