Packaging Machine Conveyor Belt

With more than 20 years of experience in industrial belt manufacturing, SHUNNAI focuses on solving common problems in modern packaging production, including inaccurate positioning, belt deviation, material slipping, frequent replacement and hygiene requirements. Our Packaging Machine Conveyor Belt solutions include PVC, PU, silicone, PTFE and customized industrial belt structures designed for different packaging equipment and operating environments.

SHUNNAI operates according to GB/T 19001-2016 / ISO 9001:2015 quality management standards and has professional certification support including FDA, MA and CNAS certification systems. From raw material inspection, fabric reinforcement, coating lamination to final cutting and testing, every production process is controlled to ensure stable quality for global customers.

Every belt undergoes strict inspection procedures including tensile strength testing, elongation measurement, surface friction evaluation, dimensional stability testing and anti-static performance verification. These quality controls allow SHUNNAI belts to operate reliably in high-speed, high-frequency and high-cleanliness packaging environments.

Matching Different Packaging Equipment

Packaging production lines include various machines with different conveying requirements. A belt that performs well on one machine may not be suitable for another application. SHUNNAI evaluates equipment structure, product characteristics, operating speed and production conditions before recommending the appropriate belt solution.

For horizontal pillow packaging machines, stable surface friction and accurate product feeding are essential because unstable conveying can cause packaging film deviation or sealing errors. For three-side seal packaging machines and labeling equipment, dimensional stability and precise running are more important to maintain consistent product positioning.

Automatic bag sewing machines require stronger wear resistance because bags may contain fertilizer, chemical materials or heavy industrial products. Carton forming and sealing equipment usually requires higher load capacity and excellent tracking stability to prevent carton accumulation and production interruption.

SHUNNAI provides customized belt structures according to different equipment requirements, including surface patterns, guide strips, sidewalls, perforations, timing profiles and special connection methods. This approach helps customers achieve better compatibility with existing packaging systems.

Improving Packaging Accuracy

In automated packaging production, conveying accuracy directly affects product appearance, sealing quality and production efficiency. Small positioning errors may lead to packaging waste, printing deviation or incorrect labeling.

SHUNNAI improves conveying accuracy through material stability and manufacturing precision. High-modulus polyester fabric reinforcement reduces belt deformation during continuous operation, helping maintain consistent length and tension performance.

The low-stretch structure provides better synchronization with servo-driven packaging machines. For high-precision applications such as film printing and label positioning, PU timing belt structures can provide accurate power transmission and reduce slip caused by friction-only driving methods.

Optional guide strips, sidewalls, vacuum holes and positioning accessories are available for applications where products require additional control during transportation. These designs help prevent carton movement, bag shifting and lightweight product deviation.

Choosing Suitable Belt Materials

Different packaging industries create different demands on conveyor materials. Selecting the correct belt material is important for production efficiency, product safety and long-term operating costs.

For food packaging applications such as biscuits, candy, meat and bakery products, PU, silicone and PTFE materials are commonly selected because of their clean surface, easy maintenance and resistance to oil contamination. These materials support hygienic production requirements and frequent cleaning processes.

For high-temperature packaging environments, silicone and PTFE solutions provide stable operation under elevated temperatures and reduce problems caused by sticking or material adhesion.

For chemical packaging, fertilizer bags and industrial material handling, wear-resistant PVC and reinforced PU structures provide stronger resistance against dust, abrasion and heavy loads.

For carton packaging and printing applications, reinforced PVC belts and PU timing belts help maintain stable conveying under repeated start-stop operation and precise positioning requirements.

Stable Operation in High-Speed Production

Modern packaging factories usually operate continuously with high production speed and frequent start-stop cycles. Under these conditions, belt deviation, surface wear and unstable friction can directly influence packaging efficiency. SHUNNAI focuses on improving running stability through optimized material structure, precise manufacturing processes and application-based testing.

During high-speed operation, belt tension changes and roller alignment are common reasons for conveying problems. SHUNNAI uses high-strength fabric reinforcement and controlled production processes to maintain dimensional stability, helping reduce adjustment frequency and unexpected downtime.

For automated packaging equipment requiring continuous operation, the connection method is also an important factor. SHUNNAI uses reliable vulcanized splicing technology, with splice strength reaching ≥90% of the base belt, helping maintain stable operation under repeated movement and heavy working conditions.

Factory Performance Verification

Before supplying global customers, SHUNNAI evaluates belt performance through practical industrial application tests. These tests focus on real production conditions instead of laboratory-only data, including cleaning frequency, load changes, operating speed and environmental exposure.

Food Packaging Production Test

Test period: 6 months

Application environment: Meat packaging line with grease exposure, daily cleaning and frequent operation.

Test results: The PU belt surface maintained stable structure without swelling or delamination. The friction coefficient remained within 0.5–0.6, with no abnormal odor or mold growth observed during continuous operation.

The test confirmed that suitable PU materials can help food manufacturers maintain cleaner conveying conditions and reduce belt replacement caused by oil and moisture exposure.

Fertilizer Bag Sewing Test

Test period: 8 months

Application environment: Automatic bag sewing line operating at 30–40 bags per minute, handling 25–50kg bags in a high-dust environment.

Test results: The reinforced PVC belt showed only slight surface wear without cracking or structural damage. Tracking deviation remained stable within ±2mm after long-term operation.

The result demonstrated that appropriate belt reinforcement can improve durability in industries where dust, abrasion and heavy loads are common.

Carton Packaging Continuous Running Test

Test period: 2,000 hours continuous operation

Application environment: Carton transportation with 15–30kg loads and frequent start-stop cycles.

Test results: Tensile strength remained above 45 N/mm under 1% elongation conditions. The splice structure remained stable, and no slipping occurred during repeated operation.

Tracking and Position Stability Test

Belt tracking accuracy is one of the most important factors for automated packaging systems. Poor tracking may cause product accumulation, incorrect labeling and packaging machine stoppage.

SHUNNAI conducted a 72-hour continuous high-speed running test at 40 m/min, simulating carton, food bag and granular material packaging applications.

Real Application Feedback

Food Packaging Production Line

“We make cooked food packaging. Our old belt absorbed oil and water, started to smell within a week, and was difficult to clean. After switching to SHUNNAI PU belt, the smooth surface rinses clean easily. After six months, there is no odor, operation remains stable, and sealing position accuracy has improved.”

– A food company in Shandong

Fertilizer Bag Sewing Line

“Fertilizer materials create a dusty and corrosive environment. Ordinary belts cracked within two to three months. The SHUNNAI belt has been running for eight months, the splice remains intact, and there is almost no slipping, saving significant maintenance time.”

– A compound fertilizer plant in Hebei

Carton Packaging Equipment

“We handle many carton sizes, some weighing up to 30kg. The previous belt often moved sideways and caused carton jams. SHUNNAI’s belt with guide strips runs smoothly without tracking problems, and after more than half a year the surface wear is still very limited.”
