PENGLAI offers a range of high quality full paper wraparound labellers with hot glue for pre-cut paper labels.

Suitable for a variety of cylindrical containers, this type of labeller uses a high quality Nordson hot glue jet dispenser. The particularly robust construction of the label dispenser and machine structure make our labellers particularly adept for use in remote areas where accessibility to technical assistance is limited.
Wrap-around labels are applied with a hot-melt adhesive in a labelling machine where before the label dispenser, containers have glue or adhesive applied to them by glue dispensing nozzles, while the rotary plates on which the containers are held in position, are temporarily stationary.

This operation allows for highly precise gluing. The containers can then be rotated counter to the direction of rotation of the labeller carousel carrying the plates, so that a precise removal of the wrap-around label from the dispenser is effected. This means that glue cannot accumulate on other labels in the box to impair the labelling operation.

Hot melt adhesive (HMA), also known as hot glue, is a form of thermoplastic adhesive that is commonly sold as solid cylindrical sticks of various diameters designed to be applied using a hot glue gun. The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure. The glue squeezed out of the heated nozzle is initially hot enough to burn and even blister skin. The glue is sticky when hot, and solidifies in a few seconds to one minute. Hot melt adhesives can also be applied by dipping or spraying, and are popular with hobbyists and crafters both for affixing and as an inexpensive alternative to resin casting.

In industrial use, hot melt adhesives provide several advantages over solvent-based adhesives. Volatile organic compounds are reduced or eliminated, and the drying or curing step is eliminated. Hot melt adhesives have long shelf life and usually can be disposed of without special precautions. Some of the disadvantages involve thermal load of the substrate, limiting use to substrates not sensitive to higher temperatures, and loss of bond strength at higher temperatures, up to complete melting of the adhesive. This can be reduced by using a reactive adhesive that after solidifying undergoes further curing e.g., by moisture (e.g., reactive urethanes and silicones), or is cured by ultraviolet radiation. Some HMAs may not be resistant to chemical attacks and weathering. HMAs do not lose thickness during solidifying; solvent-based adhesives may lose up to 50–70% of layer thickness during drying.

Applications of HMA

Hot-melt adhesives are as numerous as they are versatile. In general, hot melts are applied by extruding, rolling or spraying, and the high melt viscosity makes them ideal for porous and permeable substrates.[43] HMA are capable of bonding an array of different substrates including: rubbers, ceramics, metals, plastics, glass and wood.[40]

Today, HMA (hot-melt adhesives) are available in a variety of different types, allowing for use in a wide range of applications across several industries. For use with hobby or craft projects such as the assembly or repair of remote control foam model aircraft, and artificial floral arrangements, hot-melt sticks and hot-melt glue guns are used in the application of the adhesive. For use in industrial processes, adhesive is supplied in larger sticks and glue guns with higher melting rates. Aside from hot melt sticks, HMA can be delivered in other formats such as granular or power hot melt blocks for bulk melt processors. Larger applications of HMA traditionally use pneumatic systems to supply adhesive.[43]

Examples of industries where HMA is used includes:

Closing the flaps of corrugated boxes and paperboard cartons in the packaging industry.
Spine gluing in the bookbinding industry
Profile-wrapping, product assembly and laminating applications in the woodworking industry
Disposable diapers are constructed through the use of HMA, bonding the non-woven material to both the backsheet and the elastics.
Many electronic device manufacturers may also use an HMA to affix parts and wires, or to secure, insulate, and protect the device's components.
