Plastic Extrusion Laminating Machine

When it comes to laminating, the quality of the finished product depends on how the various materials are bonded together.plastic extrusion laminating machine The backing materials may be paper, cardboard, aluminium foil or plastic film. A variety of techniques can be used to improve the performance of these backing materials such as calendaring, flat laminating and hot melt lamination. In particular, the type of adhesive selected primarily dictates the result that will be achieved. Extrusion laminating machines are a popular alternative to dry and hot-melt lamination methods due to the lower energy consumption and better yield.

The process of extrusion laminating is similar to the production of cast film and blown films, where a melted resin such as polyethylene, ethylene-vinyl acetate copolymers or polypropylene are deposited onto a substrate.plastic extrusion laminating machine This is done by an extrusion coating line that consists of a series of counter-rotating rolls and a chill roll. The nip between the pressure and chill rolls forces the melted resin to bond with the substrate. In the case of co-extrusion, this is accomplished by two or more extruders working in tandem to form a multi-layer film.

In the process of extrusion laminating, the heated resin is deposited onto a substrate in a continuous web. Then, the resulting product is rolled up for storage or packaging. In order to make a durable and long-lasting material, it is important to choose the right plastic extrusion laminating machine. A good machine is reliable, economical and efficient, which will save you money on power consumption.

Extrusion laminating lines are capable of producing a wide range of products such as bags, film containers and protective covers. They can also be used to produce a wide range of laminated and multi-layered materials. They can be designed to meet specific customer needs. This includes choosing the right size and thickness of the material to be produced, the proper temperature for the melting process and a suitable cooling system for the resulting product.

The inner deckle system is customized in-house to reduce trim and provides uniform high speed production. The batch blender works with a variety of resins including LDPE, EAA & Masterbatch as well as PP and Metallocene. It delivers precise dosing & mixing for the co-extrusion process and provides accurate and stable coating gauge control during production. The anchor coating unit has a unique heater recycling design which helps to save energy. The rewinding splicer utilizes both gap and contact winding modes to reduce waste and to provide a smooth and even wound surface.

A heat seal layer is a necessary part of the packaging structure for many applications, especially for food packaging. It must be able to slide easily over itself and other surfaces on the machines that fabricate bags and filled packages. This requires a relatively high level of slip. Organic "slip additives" are sometimes blended into the molten polymer to achieve this.

The process of extrusion laminating can be accomplished using a single extruder or with two separate extruders in tandem (co-extrusion). A twin die system is a common configuration and can be utilized for both the co-extrusion and extrusion lamination processes.
