Pillow EVA Hot Melt Glue Production Line | JCT Machinery

Pillow EVA Hot Melt Glue Production Line

A pillow EVA hot melt glue production line fills molten EVA hot melt glue into pillow-shaped bags, producing pre-metered hot melt glue pillows that are easy to store, transport, melt and dose. JCT Machinery supplies complete pillow EVA hot melt glue production lines — from raw material storage and reactor melting to vacuum deaeration, chiller cooling, pillow filling, sealing, labelling and cartoning. If you need a pillow EVA hot melt glue production line for packaging, woodworking, bookbinding or automotive applications, the sections below cover the equipment configuration, the reactor specification, the formula and the full production process.

What Is EVA Hot Melt Glue?

EVA hot melt glue is a solvent-free, water-free, 100% solid fusible polymer. It is solid at room temperature and becomes a flowable liquid adhesive with a certain viscosity when heated and melted to a certain degree. After melting, it is light brown, translucent, or native white. Because no solvent or water is involved, an EVA hot melt glue production line is a cleaner and more energy-efficient route than solvent-based adhesive manufacturing.

What Is Pillow EVA Hot Melt Glue?

Pillow hot melt adhesive is a type of manufacturing output in which hot melt adhesive is supplied in the form of pillows or beads. Pillow EVA hot melt glue is EVA-based hot melt glue packed into pillow-shaped bags: the molten glue is metered and filled into pre-made pillow bags, sealed, cooled and packed, instead of being cast into sticks or granules. Each pillow contains a fixed amount of adhesive, so users can drop whole pillows into a melter without weighing or handling bulk glue — cleaner, safer and easier to automate. Pillow hot melt adhesive is widely used in various industries, including packaging, woodworking, bookbinding, automotive, and many others.

Reactor: The Heart of the Pillow EVA Hot Melt Glue Production Line

The reactor is responsible for controlling the temperature, pressure and mixing speed of the raw materials. The raw materials used to make hot melt adhesive pillows typically include polymers, resins, waxes and other additives. These materials are added to the reactor in specific proportions and heated to a specific temperature to create a homogeneous mixture.

The reactor plays a vital role in the pillow EVA hot melt glue production line, as it ensures that the hot melt glue produced is of consistent quality and meets the desired specifications. The reactor also helps to eliminate any impurities or contaminants that may be present in the raw materials, ensuring that the final product is of high quality — and it directly determines the melt viscosity and homogeneity that the pillow filling and sealing stages depend on.

EVA Hot Melt Glue Formula

The reactor and the downstream units of the pillow EVA hot melt glue production line are configured around this formula, so the same line can run different recipes without changing the overall process flow.

How the Pillow EVA Hot Melt Glue Production Process Works

1. Feeding and storage — EVA resin, tackifying resin, wax and additives are delivered from the raw material storage system. Liquid raw materials are fed with a gear pump or diaphragm pump, powder raw materials with pneumatic conveying or a screw feeder, and granular raw materials with a screw feeder or vibrating feeder.
2. Melting and mixing — the raw materials are added to the reactor in specific proportions, heated to a specific temperature and mixed into a homogeneous melt under controlled temperature, pressure and mixing speed.
3. Vacuum deaeration — the vacuum system, supported by the condenser, removes any air or other gases trapped in the adhesive so the melt stays homogeneous and free of bubbles and other defects.
4. Transfer — the homogeneous melt is transferred through the transfer tank to the pillow filling machine.
5. Pillow filling and sealing — the pillow filling machine fills pre-made pillow bags with a pre-set amount of adhesive, and the sealing machine applies a controlled amount of heat and pressure to seal each pillow securely.
6. Cooling — the chiller system and cooling system cool the filled pillows at a consistent temperature and cooling rate, preventing the hot melt glue from overheating or becoming too viscous.
7. Drying and conveying — the drying / conveying system transports the cooled, sealed pillows to the packaging stage.
8. Labelling and cartoning — the packing system applies product codes, batch numbers, manufacturing dates and product specifications to each pillow, then packs a fixed number of pillows into boxes for shipping.

Consistent Glue Shape: Solving the Tail (Wire-Drawing) Problem

JCT found that some hot melt glue products produced by some production line equipment on the market have tails (i.e. the shape is not smooth enough, and there is a phenomenon of drawing or tailing). Choosing JCT's equipment can prevent this from happening.

1. High-precision cutting technology system ensures perfect shape and eliminates wire drawing tails.
2. Accurate temperature control system optimizes glue viscosity to prevent cutting wire drawing.
3. Advanced water cooling / air cooling system ensures rapid shaping.
4. Intelligent automatic control, precise adjustment of production parameters, stable and consistent production results.
    

FAQ: Pillow EVA Hot Melt Glue Production Line and Reactor

Q: What is a pillow EVA hot melt glue production line?

A: It is a manufacturing line that produces hot melt adhesive in the form of pillows or bags. The line melts, mixes and deaerates EVA-based hot melt glue in a reactor, then fills it into pre-made pillow bags, seals, cools, labels and packs them. A typical configuration includes a raw material storage system, a reactor, a transfer tank, a vacuum system, a condenser, a wrapping system, a chiller system, a cooling system, a drying / conveying system and a packing system.

Q: What is the function of the reactor in a pillow EVA hot melt glue production line?

A: The reactor controls the temperature, pressure and mixing speed of the raw materials. It melts and mixes polymers, resins, waxes and additives into a homogeneous mixture, removes impurities and contaminants, and determines the viscosity and homogeneity that the pillow filling and sealing stages depend on.

Q: What capacity of reactor is available for a pillow EVA hot melt glue production line?

A: JCT Machinery offers 500 L, 1000 L, 5000 L and 10 T reactors, all jacketed vessels with a mechanical agitator, pressure relief valve, operating temperature up to 200 °C and operating pressure up to 1.6 MPa.

Q: What is the difference between pillow hot melt glue and granular hot melt glue?

A: Both start from the same EVA hot melt glue formula and the same reactor melting process. The difference is the delivery form: granular hot melt glue is cut into granules by an underwater granulator, dried and screened, while pillow hot melt glue is metered and filled into pillow-shaped bags, then sealed, cooled, labelled and cartoned.

Q: Why do some hot melt glue products have tails?

A: Tails (a non-smooth shape with drawing or tailing) usually come from unstable cutting temperature and inaccurate temperature or viscosity control. JCT's high-precision cutting technology, accurate temperature control and rapid water / air cooling keep the shape consistent and eliminate wire drawing tails.
