Material Characteristics

The material selection of a conveyor belt directly affects safety, durability and application performance. SHUNNAI uses food-grade polyethylene as the belt cover material, combined with a high-modulus polyester fabric carcass to achieve a balance between lightweight structure and mechanical strength.

Food-grade PE Structure

Polyethylene is odorless, non-toxic and chemically stable, with low water absorption and excellent electrical insulation properties. The material complies with FDA and GB4806 food contact safety standards, allowing direct contact with sensitive materials including food, tobacco and pharmaceutical products.

Compared with materials that may absorb odors or retain residues, the PE surface provides better cleanliness performance. Its dense structure reduces contamination risks and supports frequent cleaning processes in high-hygiene production environments.

Stable Layer Bonding

The SHUNNAI PE belt is manufactured through high-temperature calendering technology, allowing the cover layer and polyester carcass to achieve strong adhesion. The structure reduces the possibility of layer separation during continuous operation.

The high-modulus polyester reinforcement provides dimensional stability and helps maintain accurate belt tracking during long-distance conveying. This feature is especially suitable for light-load conveying systems requiring stable operation.

Performance in Special Conditions

Different industries have unique requirements for conveyor belt materials. SHUNNAI Polyolefin PE TPO conveyor belts are developed for applications where ordinary belt materials may not provide sufficient performance.

Cold Chain Operation

Low-temperature environments can cause some belt materials to harden, lose flexibility or develop cracks during long-term operation. PE material naturally maintains toughness in cold conditions, allowing SHUNNAI belts to remain flexible in quick-freeze tunnels, frozen food workshops and ice cream production lines.

The stable structure helps reduce deformation and maintains transmission performance in sub-zero environments, supporting continuous cold chain production.

Clean Material Conveying

For tobacco processing, pharmaceutical materials and photosensitive products, odor transfer, dust accumulation and material contamination are major concerns. PE material is chemically inert and does not easily absorb external odors, making it suitable for industries requiring high material purity.

The smooth surface reduces powder adhesion and static dust attraction, helping maintain cleaner conveying conditions for sensitive products.

Surface Design Options

Different products require different levels of friction and surface performance. SHUNNAI provides multiple surface designs to meet various conveying conditions, including flat conveying, inclined transportation and wet working environments.

Smooth Surface

Smooth PE surfaces are suitable for frozen food, powders, pharmaceuticals and other applications where easy cleaning and direct material contact are required. The non-abrasive surface helps reduce product damage and simplifies maintenance.

Patterned Surface

For inclined or slip-sensitive applications, SHUNNAI offers diamond, longitudinal stripe, herringbone and round dot patterns. These structures improve friction performance while reducing material sliding and accumulation.

Surface patterns can be selected according to product shape, conveying angle and production environment, helping customers achieve stable transportation performance.

Hygiene Enhancement

For food, pharmaceutical and other high-cleanliness industries, conveyor belt hygiene directly affects product safety and production efficiency. SHUNNAI Polyolefin PE TPO conveyor belts feature a smooth, dense surface structure that reduces residue accumulation and simplifies daily cleaning procedures.

Easy Cleaning Performance

The non-porous PE surface does not easily absorb oil, moisture or odors, making it suitable for production environments requiring frequent sanitation. High-pressure water cleaning and neutral cleaning agents can be used to maintain a clean conveying surface and reduce downtime caused by complex maintenance procedures.

For meat processing, dairy production and other bacteria-sensitive applications, SHUNNAI can provide antibacterial and mold-proof modifications to help inhibit microbial growth and support longer continuous production cycles.

Safe Material Contact

SHUNNAI PE belts are manufactured with food-grade polyethylene materials and comply with FDA and GB4806 food contact safety standards. The material is odorless, non-toxic and does not easily transfer taste or smell to conveyed products.

This makes them suitable for direct contact applications involving food, tobacco, pharmaceuticals and other sensitive materials where contamination control is important.

Application Validation

SHUNNAI Polyolefin PE TPO conveyor belts have been applied in multiple production environments where cleanliness, low-temperature performance and material stability are required. These applications demonstrate the advantages of PE materials in specific conveying conditions.

Frozen Food Conveying

In cold chain sorting rooms, frozen meat temporary storage areas and ice cream quick-freeze tunnels, SHUNNAI PE belts maintain flexibility under low-temperature and high-humidity conditions. The material does not become brittle or lose structural stability during long-term operation.

A large quick-frozen food factory in Northeast China replaced its existing belt with SHUNNAI PE on a fluidized quick-freeze tunnel. The new belt extended replacement intervals by more than six months due to improved low-temperature stability and durability.

Tobacco Processing Lines

Tobacco processing environments require strict control of odor transfer, dust generation and material contamination. Traditional belt materials may release particles or absorb odors after long-term operation, affecting product quality.

SHUNNAI food-grade PE belts provide an odor-neutral surface with low dust attraction characteristics. According to feedback from a major Chinese tobacco factory, replacing conventional belts with SHUNNAI PE belts reduced cleaning frequency and improved tobacco quality stability.

Bakery Cooling Systems

After baking, bread and biscuits require clean and stable cooling transportation. The white PE surface used by SHUNNAI does not absorb oil or grease and does not easily collect crumbs, helping maintain a cleaner conveying environment.

Combined with automatic crumb cleaning equipment, SHUNNAI PE belts can support continuous bakery production while reducing foreign matter risks and manual cleaning requirements.

Structural Customization
