Plastic corrugated hollow sheet box making process

1,Raw material perpare
The PP filler masterbatch granulating machine  for the raw material production.
The waste PP plastic sheet can be cutting into small chip to use directly,or the waste chip after granulating then for extruder.
The PP granules and filler masterbatch and coloe pigment can be mixing for the extruder.

2,PP hollow corrugated sheet production line

Tongsan professional for  plastic PP hollow corrugated sheet  making machine ,we can provide all series production line for the sheet width range from 1220mm to 2800mm ,the  corrugated sheet thickness range from 2-6mm or 7-12mm.

3,Plastic corrugated box making machine

Corona treatment machine for the surface treatment
In order to improve the surface tension of the hollow sheet surface, and thereby improve the printing ink fastness, the hollow corrugated sheet surface will under corona treatment, so that the surface produces micro-concave dense holes, plastic surface roughening, increase the surface activity.

Box sheet  printer machine
The printing machine generally consists of a mechanism such as plate loading, ink coating, embossing, and paper feeding (including folding). It works by first making a plate and image to be printed on a printing press, then applying the ink to the place where the text and image are printed on the printing plate by hand or by a printing machine, and then directly or indirectly Printed on paper or other substrates (such as textiles, metal sheets, plastics, leather, wood, glass, and ceramics) to replicate the same print as the plate.

Die cutting machine for the shape of corrugated box,
The working principle of the die-cutting machine is to use a die-cutting knife, a steel knife, a metal mold, a steel wire (or a template carved from a steel plate), and apply a certain pressure through the plate to cut the printed product or the cardboard into a certain shape. If the entire print is pressed into a single graphic product, it is called die cutting; if the steel wire is used to press a mark on the printed product or leave a bent groove, it is called an indentation.

Welding machine or bookbind  edge sealing  machine
Plastic welding machines are used to weld thermoplastic engineering plastic sheets or products such as polyethylene, polypropylene, polypropylene, and nylon. During operation, the plastic electrode is melted and melted, and the workpiece to be welded is fused and bonded. It is widely used in the welding and maintenance of plastic equipment, plastic floor laying, plastic pipe connection, plastic bottle sealing and so on.

I, overview and market prospects:

The introduction of PP hollow sheet material will be a landmark start in the packaging industry. With advantage of low loss, effectively recyclable, simple production process, low labor cost, The PP hollow sheet is used to replace the carton packaging in packaging industry. The PP hollow sheet can be fully recycled after using and no loss in the production process, so that the packaging reached a real sense of environmental protection and reuse.

Relative to the existing carton packaging market, the PP hollow sheet material launch time is shorter, the market share is not high, in the context of the state's efforts to environmental management, carton packaging will slowly withdraw from the market, but also with the Consumer awareness of environmental protection, PP hollow sheet will basically occupy the packaging industry in the high-end market.

Market-oriented, environmental protection as a concept, conducted a large number of scientific experiments, the successful development of a PP hollow sheet production line, is now fully market. Companies from manufacturing equipment to the process, process formula, installation and commissioning, staff training, such as through-train service.

II, characteristics and market advantages:

1, PP hollow sheet is mainly used in various fields of electronics, packaging, machinery, light industry, postal services, food, medicine, pesticides, home appliances, advertising, decorating, stationery, magneto-optical technology, bioengineering medicine and health. It is a new type of environmentally friendly packaging materials.

2, PP hollow board is a green material with a very wide range of applications, and gradually replace some of corrugated paper packaging materials, and now some domestic enterprises are also being developed for building decoration materials. because of its wide range of applications, easy to use, PP hollow sheet also has been called as "Universal board", which is widely used in advertising background, stationery materials, industrial packaging, products such as earthquake, the most common products like turnover box, removable combo box, finished packaging Boxes and boxes in the partition. PP hollow sheets are generally made of environmentally friendly non-polluting recyclable thermoplastic polypropylene (PP), polyethylene (HDPE) resin and a variety of accessories made of the other there is a polycarbonate (PC) PP hollow sheet, also known as sunshine board, Long board, PC hollow board, is a high-performance engineering plastics PC resin processing, with high transparency, light weight, impact resistance, noise, heat insulation, flame retardant, anti-aging characteristics, is a high-tech, integrated Extremely superior performance, energy saving and environmentally friendly plastic sheet

3, PP hollow sheet standardized products can be reused many times, can bring huge social and economic benefits, making the plate less than one-tenth of the cost of disposable tray, but also can improve the volume of loading and inventory utilization, Improve logistics efficiency, significantly reduce logistics costs. At the same time, the General Office of the State Council forwards the notice of the NDRC and other departments on accelerating the conservation and substitution of timber. It explicitly requires that all industries speed up the implementation of timber conservation and substitution technologies and make green Environmentally friendly products.

How to make the PP corrugated hollow box for packaging
PP hollow sheet turnover box main material is a PP hollow sheet, and then after the pressure cut, torn edges, stitching, assembly and made of a series of processing flow.

Below is the example of processing for turnover box
1, the extrusion line produce the required PP hollow sheets with required width and thickness, and cut into required length. And collecting different sizes in different stacking.
2,Use the pressure cutting machine to cut the PP hollow sheet into required shape. Pressing action should be accurate, rapid, agile, and keep the board clean, in accordance with the provisions of a unified placed on the table
3, the professional workers tear the extra edges according to the indentation from the pressure cutting machine, The tearing action should pay attention to the intensity. to ensure the board neat appearance, it is not allowed to produce flash and laceration because of strong tearing force.
4, stitching the two sheets by rivets, flat wire or welding, etc., the stitching seal can be sealed by fiber tape or glue or magic paste.
5, quality inspection. Quality inspection staff to perform full inspection, sampling, failure and other standard scrap process.
6, the qualified products will be packaged and stored, when folded, the packing box should be labeled and neatly put into storage.
The above is the whole process of making the turnover box from the PP hollow sheet. The turnover box made from PP hollow sheet has the advantages of light weight, non-toxic, tasteless, no pollution, flexural resistance, anti-aging, waterproof, moisture proof, abrasion resistance, corrosion resistance, , Can be reused repeatedly and a series of advantages, is a new type of green materials, logistics and packaging industry in the transport plays an important role in storage and turnover, can effectively protect the product from the external environment damage..
