Co-Extrusion Lamination Machine for Food Flexible Packaging

The primary processes used to make flexible packaging are extrusion, co-extrusion, lamination, and extrusion coating.co-extrusion lamination machine for food flexible Each has its unique applications and advantages. For example, co-extrusion allows for the formation of multilayer structures that would be impractical to produce in a single extrusion step. The resulting structure has layers of different polymer materials that are combined together and then extruded into one piece. This enables the production of different products such as food films, agro film, tubes and bottles, etc. This is very useful in the food industry because it can prevent oxidation of the product, thus extending shelf life and enhancing food safety.

The benefits of co-extrusion machine are numerous, but it is important to carefully consider the requirements for a project before selecting this type of equipment.co-extrusion lamination machine for food flexible First, it is essential to determine the purpose of the structure and what the requirements are for printing, barrier properties and structural strength. Then, it is necessary to know what the temperature range of the structure will be. If it will be exposed to high temperatures, it will require a layer of a material with a higher Tg (glass transition temperature) than the other layers.

For example, if the packaging is for food products and will be subject to microwave heating, it will need a barrier layer that can withstand the temperatures of the microwave. The barrier layer also needs to be able to keep oxygen out of the food, which can cause spoilage. Another consideration is whether the flexible packaging will need a layer that can resist puncture or tear.

A co-extrusion system can help meet these requirements by incorporating multiple layers of plastics that have different properties and characteristics. The system is also able to control the thickness of each layer. The layers can be produced in a continuous process that is more efficient than the traditional method of applying an adhesive to two separate pieces of plastic film or paper.

Uflex’s Engineering Business division will be displaying a fully-automatic extrusion lamination machine at PLASTINDIA next month. The EL-1300 machine is capable of co-extrusion as well as tandem extrusion, making it an ideal choice for converting companies that need the functionality of both processes. The company’s EL-1300 was launched last year, after receiving positive feedback from Indian converters. It has since undergone value-engineering to enable co-extrusion and dual extrusion.

The company has also developed an auto-splicing function that allows for more accurate splicing and higher output. It can be used for a variety of applications, such as film packs for snacks and retort foods, paper packaging for milk and liquor, and non-woven bags. It is capable of producing laminated materials with a wide variety of substrates including paper, PET, PP and PVC film, woven or non-woven fabric, aluminium foil and glass fibre scrim. It can also be used to produce multilayer structures with a foam core and two outer skins. This system can also be used to create large blow molded parts such as bottles and trays.
