Heat-Sealing Coating

In the adhesives area, thermoplastic, fatty polyamides are used in hot-melt and heat-seal adhesives for leather, paper, plastic and metal. Blends of EDA- and DETA-based polyamides are suggested for use in metal can seam sealants with improved toughness (234) pressure sensitive adhesives have been formulated with DETA-based polyamides (235) and anionic and cationic suspensoid adhesives are used as heat-seal coatings in paper converting (236). PIP and certain PIP derivatives are used with EDA in some appHcations (237). [Pg.47]

Ethylene acid polymer is obtained by the copolymerisation of ethylene with either acrylic or methacrylic acid. These copolymers are somewhat similar to LDPE and are found as ethylene acrylic acid (EAA) and ethylene methacrylic acid (EMA). Both are used in various packaging applications, i.e. flexible packaging, adhesive laminating, hot melts, and heat seal coatings. [Pg.190]

Most films can be sealed by some means—direct heat, hot air, ultrasonic, HF or RF, etc. Some need special heat seal coatings. [Pg.266]

Sachets can be fabricated from a single web with a centre fold, using a three or four sided seal or two webs using a four sided seal. The reels may be fed horizontally or vertically and be sealed by a series of heated platens or rollers (cylinders) or a combination of the two. In certain ways they are an enlarged version of a strip pack. The sachet seal can also be made peelable by a non-seal part on the web which may involve a pattern lacquer rather than a full heat seal coating. Difficult to tear plies, like PET, can also be used provided a cut or V-notch is added to initiate the tear. [Pg.378]

Due to adhesion and flexural properties, the dimer acid-based polyesters are used as lubricants, adhesives and formed the basis of flexographic inks and heat seal coatings. They are used as vibration dampers when sandwiched between metal sheets [58]. [Pg.587]

At elevated temperatures, the ester loses its inactive role as modifier-extender and functions as plasticizer or even solvent for some polymers. This bifunctional property makes it a valuable component of heat-seal coatings and hot-melt adhesives. [Pg.216]

This group includes heat-sealing adhesives and high-frequency (HF) sensitive heat-seal coats these are coating adhesives that are heat-activated during bonding. Contact adhesives and pressure-sensitive adhesives bond by the same principle but without the action of heat. [Pg.23]
