Saipu Invites Global Buyers to All in Print China 2026: How to Choose the Right Hot Melt Adhesive Equipment for Printing and Packaging

Saipu Electromechanical Device Co., Ltd. sincerely invites printing manufacturers, packaging converters, bookbinding companies, paper product manufacturers and industrial equipment buyers to visit us at The 10th China International All in Print Exhibition and China International Printing Technology and Equipment Exhibition, taking place from October 12–16, 2026, at the Shanghai New International Expo Centre, China.

Booth Number: E5C405

As printing and packaging manufacturers continue to improve production efficiency, adhesive application has become an important factor in bonding quality, material consumption and automated line performance. Selecting the right hot melt adhesive equipment is therefore not simply a matter of comparing machine prices or heating capacity. Buyers also need to consider adhesive compatibility, dispensing accuracy, production speed, nozzle configuration and maintenance requirements.

At Booth E5C405, Saipu welcomes visitors to discuss practical hot melt adhesive application requirements and equipment solutions for printing-related manufacturing, packaging, bookbinding, paper products and other industrial bonding processes.

Whether you are upgrading an existing production line, addressing unstable glue application or evaluating new automation equipment, this exhibition is an opportunity to identify a hot melt adhesive system that fits your actual production needs.

1. The Buyer Problem: Why Can Adhesive Application Become a Production Bottleneck?

In printing, packaging and paper product manufacturing, adhesive application must meet several requirements simultaneously:

• Consistent glue output during continuous production

• Suitable adhesive quantity for each product

• Reliable bonding between different substrates

• Clean adhesive application with minimal stringing

• Stable performance during production starts and stops

• Compatibility with automated equipment

• Practical maintenance and cleaning procedures

When the adhesive system is not correctly matched to the process, manufacturers may encounter uneven bonding, excessive glue consumption, nozzle blockage, adhesive residue, production interruptions and unnecessary rework.

For example, a bookbinding line may require a controlled adhesive bead, while a packaging line may need rapid application synchronized with product movement. A paper product manufacturer using a spray process may have different requirements for coverage and adhesive distribution.

These processes cannot always be served effectively by the same equipment configuration.

The key procurement question is:

How can you select hot melt adhesive equipment that matches your adhesive, substrate, application pattern and production speed?

The answer begins with understanding the complete bonding process rather than focusing on a single machine specification.

2. Product Selection: Which Hot Melt Adhesive Equipment Should You Consider?

Before purchasing a hot melt glue machine, identify the application method required by your production line.

The appropriate configuration depends on the product structure, adhesive type and bonding method.

Spray application

Spray application is worth evaluating when adhesive needs to cover a relatively broad area or follow a defined pattern. The nozzle configuration, spray width and adhesive output must match the substrate and production speed.

Bead or line application

Bead application is suitable for processes requiring adhesive to be deposited along a defined path. Buyers should evaluate bead consistency, application position, start/stop response and glue output.

Automated dispensing

For automated production lines, the adhesive system may need to coordinate with conveyors, sensors, robotic equipment or PLC controls. The timing of adhesive delivery is as important as the nominal output capacity.

Procurement recommendation: Choose the application method first, then select the melting system, pump, hose, applicator and nozzle configuration around the process.

3. Technical Parameters: What Should Buyers Check Before Purchasing?

When comparing hot melt adhesive equipment at an exhibition, use the same technical checklist for every supplier.

3.1 Adhesive type and viscosity

Start by confirming which adhesive will be used.

Common categories include EVA, PUR, PSA, PO and other specialty hot melt formulations. Their processing temperatures, viscosity characteristics and handling requirements may differ.

Ask the supplier to confirm that the proposed equipment is suitable for your specific adhesive. If you have an adhesive technical data sheet, bring it to the discussion.

For reactive PUR adhesives, also evaluate moisture management, sealing, shutdown procedures and the protection of the adhesive delivery path.

3.2 Adhesive output

The required glue output depends on adhesive consumption and production volume.

A useful initial calculation is:

Required adhesive output (kg/h) = adhesive consumption (g/product) × production rate (products/h) ÷ 1,000

For example, if a production line consumes an average of 2 g of adhesive per product and produces 10,000 products per hour, the theoretical adhesive demand is 20 kg/h.

This is an illustrative calculation, not a machine recommendation. Actual equipment selection should account for the application pattern, operating cycle, number of dispensing points and process requirements.

Buyers should ask suppliers about both maximum output and the ability to maintain stable delivery at the intended operating conditions.

3.3 Temperature control

Hot melt adhesive temperature affects viscosity and flow behavior.

When evaluating a machine, ask about:

• Melter temperature control

• Heated hose configuration

• Applicator temperature control

• Sensor type and placement

• Temperature recovery during production

• Protection against overheating

A stable temperature throughout the adhesive delivery path can help maintain consistent flow. The correct operating temperature must always follow the adhesive manufacturer's recommendations.

3.4 Pump and pressure

Pump performance influences adhesive delivery, particularly when production requires continuous operation or multiple application points.

Confirm:

• Pump type

• Maximum working pressure

• Flow adjustment method

• Number of outlets

• Compatibility with adhesive viscosity

• Availability of maintenance parts

Maximum pressure alone does not determine dispensing quality. The pump, adhesive, hose, applicator and nozzle must work as a coordinated system.

3.5 Nozzle and applicator configuration

The applicator determines how adhesive reaches the product.

Depending on the process, buyers may require a spray, bead, line or other dispensing configuration.

Check the required application width, glue quantity, dispensing distance, product movement and start/stop behavior. If nozzle blockage or adhesive stringing is already a problem on your production line, discuss the complete adhesive path rather than replacing the nozzle without diagnosing the cause.

3.6 Automation and control

For manufacturers upgrading automated lines, consider whether the equipment can integrate with the existing control system.

Relevant questions include:

• Can adhesive delivery be synchronized with product movement?

• Can the system support automatic start/stop signals?

• Can operating parameters be adjusted for different products?

• Is the control interface compatible with the production line?

• How are abnormal conditions identified and handled?

These details help determine whether the equipment can fit the factory's actual workflow.

4. Application Scenarios: Where Can Hot Melt Adhesive Equipment Support Production?

Saipu Electromechanical Device Co., Ltd. focuses on hot melt adhesive machinery for industrial bonding applications across multiple sectors.

Bookbinding and printed products

Bookbinding may require consistent adhesive application along defined bonding areas. Buyers should evaluate the adhesive formulation, required bond structure, application quantity and production speed before selecting equipment.

Carton and paper packaging

Packaging production often emphasizes fast bonding, repeatable adhesive placement and compatibility with automated handling.

The system should deliver the required glue quantity without creating unnecessary buildup or interfering with downstream operations.

Gift boxes and specialty packaging

Specialty packaging can involve different paper grades, board structures, folding designs and bonding positions. The adhesive system should match the product geometry and application method.

Flexible packaging and bags

Courier bags, handle bags and other packaging products may require controlled adhesive placement at specific positions. For these applications, synchronization between adhesive dispensing and product movement is an important selection consideration.

Composite and lamination processes

When bonding films, fabrics, nonwovens or other layered materials, manufacturers should evaluate the required adhesive distribution and compatibility with the substrates.

Furniture and profile-related manufacturing

Hot melt adhesive equipment can also support applications such as edge banding, profile wrapping and related bonding processes. These applications may require continuous adhesive supply and stable delivery at the specified production speed.

Other industrial applications

Depending on the adhesive and process, hot melt systems may also be used in mattress manufacturing, automotive interior bonding, leather goods, footwear and air filter production.

The correct equipment configuration varies by application. Buyers should confirm suitability through technical review and, where practical, trials using the actual adhesive and substrate.

6. Factory Solution: How Does Saipu Approach Hot Melt Adhesive Equipment Selection?

Saipu Electromechanical Device Co., Ltd. provides hot melt adhesive spraying machinery and application-oriented bonding solutions.

Rather than choosing a configuration based only on nominal machine capacity, the selection process should begin with the customer's actual manufacturing requirements.

Step 1: Understand the adhesive

Confirm the adhesive type, viscosity, recommended processing temperature and handling requirements.

Step 2: Understand the product and substrate

Identify the materials being bonded, the bonding area, product dimensions and required adhesive pattern.

Step 3: Define production targets

Determine the production speed, adhesive consumption, number of dispensing points, operating hours and frequency of product changeovers.

Step 4: Match the equipment configuration

Evaluate the melting system, pump, heating arrangement, filtration, hose, applicator, nozzle and control system as a complete unit.

Step 5: Review integration and maintenance

Confirm how the machine will connect to the production line, how operators will adjust parameters and how routine maintenance will be performed.

Step 6: Validate the process

Where possible, use the actual adhesive and substrate to evaluate application consistency, glue consumption, bonding quality and operating stability.

This approach helps buyers assess the whole production process rather than selecting a machine based on one specification.
