Acid Resistance Gluing Nozzle For Cigarette Packers

Glue Applicator / Glue Gun is a component assembled in both cigarette makers and packers, applying glue to different paper materials.

1. Payment Terms:

Payment options are negotiable to a certain extent under below principles:

For products of customized specification, or painted as required, or of special materials, we need full payment upon ordering.

For products we have in stock, normally we ask for full payment upon shipment.

For regular size wear parts/ consumables/ spares, normally we request 50% down payment before sending order to our plant, and the balance before shipment.

1. Properties

Melt viscosity

One of the most noticeable properties. Influences the spread of applied adhesive, and the wetting of the surfaces. Temperature-dependent, higher temperature lowers viscosity.

A value roughly inversely proportional to the molecular weight of the base polymer. High melt flow index adhesives are easy to apply but have poor mechanical properties due to shorter polymer chains. Low melt flow index adhesives have better properties but are more difficult to apply.

Melt flow index

1. Polymer

This can be achieved by using polymers undergoing curing with residual moisture (e.g., reactive polyurethanes, silicones), exposure to ultraviolet radiation, electron irradiation, or by other methods.Increase of bond strength and service temperature can be achieved by formation of cross-links in the polymer after solidification.
