pp/ps sheet extrusion production line is common for single-extruder single-layer sheet production line and double-extruder co-extrusion three-layer sheet production line. There are also multi-extruder co-extrusion multi-layer production line, which can process 7-9 layers of composite sheet at most, such as high-barrier evoh multi-layer co-extrusion production line. This type of extrusion line can process pp, ps, pe and other polyolefin materials.

gwell pp/ps sheet production line:

multi-extruder co-extrusion technology is adopted to produce multi-layer co-extrusion composite pp and ps sheet, such as aba, abcba, abcdcba and other multi-layer structure, which is widely used in heat forming, printing, hardware packaging, electronic tray, flocking, food, clothing, tools, toys, stationery pieces, decorative pieces and so on.

* equipped with precise distributor, evenly layered, adjustable proportion of each layer, digital precise control.

* inclined horizontal structure, easy to operate and maintain.

* roller independent power, linear speed and extruder speed synchronous closed-loop control.

* the whole machine adopts plc control to realize automatic control of parameter setting, data operation, feedback, alarm and other functions.

* gwell independently wrote the electronic control operating system

main applications of pp/ps sheet:

* pp/ps blister sheet

* pp/ps single layer sheet, pp/ps co-extruded two-color sheet, pp double-sided high-transparency sheet, etc. Sheet used in blister packaging industry.

* pp stationery sheet

* pp transparent sheet, frosted sheet (coarse sand, fine sand), two-color sheet used in stationery packaging industry sheet.

* pp foam sheet, pp foam sheet has unique advantages, pp foam sheet with density of over 0.45g/m3 has a good bending resilience, not easy to deformation, so it has a broad prospect in the field of folders; pp foam sheet with density of 0.6g/m3 has good mechanical prop

1. Stone paper product introduction:

stone paper is a kind of new material between paper and plastic, which can not only replace part of the traditional functional paper, professional paper, but also replace most of the traditional plastic packaging. With the characteristics of low cost and controllable degradation, it can save a lot of cost for users and will not produce pollution. From the point of view about replacing part of the traditional paper, it can save a lot of forest resources for the society and reduce the secondary pollution in the paper making process. From the perspective of replacing part of the traditional plastic packaging, it can save a lot of strategic resources of petroleum for the country (2.3 tons of petroleum can be saved when every 1 ton is used), and the product can degrade after using without causing secondary white pollution. Stone paper, a new environmental protection material, is a sunrise industry with strong vitality.

2. Product features:

stone paper production process is simple; large investment, high output and low energy consumption; do not need to use plant fiber, do not need to cut down trees, and it can save a lot of wood and protect the natural ecology; also it do not need to add strong acid, strong alkali, bleach and other chemical raw materials and will not discharge waste water, waste residue and toxic and harmful gas, so it belongs to the green environmental protection products. The product has good mechanical performance, waterproof, moisture-proof, moth-proofing, folding resistance, tear resistance, oil resistance, non-toxic, odorless, pollution-free, geometric size stability, high printing clarity. After discarded, it can be naturally degraded into powder to return to nature.

eva solar film extrusion production line with low temperature process

eva solar cell film is used for the encapsulation of solar cells. After laminating and curing, it is bonded and sealed, which plays a role in high light transmittance, preventing water vapor penetration, high and low temperature resistance and ultraviolet light resistance of the battery components, and ensures the stable and efficient use of the battery components. It is a kind of durable and reliable packaging material. Gwell machinery eva solar film production line is in a monopolistic global leader.

characteristics of gwell eva film production line:

(1) eva single screw extruder is used for extrusion, and the barrel constant temperature circulating water cooling system solves the technical difficulties of eva plasticizing and non-crosslinking.

(2) double-sided embossing is adopted for the roller body, and technical difficulties of adhesive roller are solved.

(3) the cooling part adopts the cooling roller and the stress relief cold bed to make the film run smoothly and fully finalize the design, ensuring the shrinkage rate is less than 3%.

(4) the whole line adopts plc automatic control to realize man-machine interface operation.

(5) the production line is equipped with online quality monitoring and control system to ensure the product qualification rate.
