French chemical company Arkema has launched a new adhesive Lotader 4613 as a part of its range of tie layers used for laminating difficult packaging films, including oxygen barrier films.
The new product can reduce costs since it can eliminate the use for primers and facilitate the designing for flexible packaging film.
It can also increase the speed for production by removing the requirement of additional steps for bonding in multilayer structures for reverse printing films.
The adhesive can be extruded at a temperature 20°C lower than the firm's previous product Lotader 4503, which in turn, lead to energy savings.
Lotader 4503 is a general purpose ready-to-use tie layer for unprimed films developed by the company.
Lotader 4613 can also be used for bonding unprimed reverse printing films with metallised films at a lamination speed which was difficult with Lotader 4503 tie layer. It can also allow users to choose 'between the possibility to either increase the bond strength between the laminated films or increase their productivity while keeping an acceptable bond strength', Arkema said.
The adhesive also has a melting temperature close to 100°C, which can promise improved thermal-resistance of the final package structure.
Besides Lotader 4613 and Lotader 4503, the product variants under Arkema's tie layer range for extrusion lamination also include Lotader 3210, Lotader 4210, Lotader 3410 and Lotader 3430.
