PP polypropylene strap

PP polypropylene strap

The main raw material for PP strapping is PP (polypropylene), which is mainly derived from petroleum or coal. Due to the different composition, PP strapping can generally be divided into the following dimensions according to function:

1 new material PP strapping

This type is the most common form of PP strapping. According to the specifications, each manufacturer can use a certain amount of PP strapping equipment or improve the blanking links and temperature control channels of existing equipment to provide products that meet the standards.

2. Recycling material PP strapping

This is based on the performance conditions of the lightweight packing belt, and at the same time reducing the cost and selecting high-performance recycling materials for production. It is a high-imitation or PP quality packing belt A goods, reasonable selection has a certain economic value, but the performance parameters can not be stable output. The main reason is that the control of recycled raw materials cannot meet the stability of raw material parameters;

3. Environmental protection PP strapping

Adopt the new specifications of T30s Polypropylene, and add anti-oxygen equipment within 0.5% to handle or replace.

4.3000 meters above/volume

10KG; now the core enterprise of domestic leading technology (eg: Chongqing Wanda Packaging Manufacturing Co., Ltd. has been able to control the PP strapping to 3000-8000 meters per roll; this type of product is mainly used in high-end products such as high-end electronics and pharmaceuticals Packaging, this type of specification is generally custom-made to limit production, so the price is higher; equipment needs to use dedicated strapping equipment (PP packaging equipment), the general domestic Elantra Chengdu provides, foreign mainly concentrated in Mosica and other advanced enterprises monopoly, equipment The price is generally more than 200,000.

PP strapping production knowledge and technical analysis

PP strapping belt is also called light strapping. It usually goes through the following seven production processes: plastic pellet melting - press belt - forming - cooling - winding - packaging - storage.

PP straps generally have the following specifications:

1.2000 meters/volume

10KG; This type is mainly applicable to customers with high requirements on the breaking force of the strapping belt. Generally, the weight of the packaged object is more than 200 kg or the baler equipment cannot be updated. The PP strapping special balers are used in the case of PP strapping. client;

2.2700 meters/volume

10KG; This type is mainly applicable to customers with high requirements for the breakage force of the strapping belt, and for customers with relatively loose control of the cost, the packaging material between 100-200KG or the baler used can not be fully used efficiently. Thin PP strapping case;

3. 3000 meters/volume

10KG; This is the standard product of PP strapping, 3.3g/m technical standard, to ensure the high quality of product quality, and at the same time to ensure the cost optimization, the need to use light strapping special automatic/semi-automatic baler (bundling machine) Or the gap between the cutters of the original equipment is changed or replaced. Every manufacturer who can provide the PP strapping belt now has the ability to process or replace the original equipment.

4. Above 3000 meters/volume

10KG; now the core enterprise of domestic leading technology (eg: Chongqing Wanda Packaging Manufacturing Co., Ltd. has been able to control the PP strapping to 3000-8000 meters per roll; this type of product is mainly used in high-end products such as high-end electronics and pharmaceuticals Packaging, this type of specification is generally custom-made to limit production, so the price is higher; equipment needs to use dedicated strapping equipment (PP packaging equipment), the general domestic Elantra Chengdu provides, foreign mainly concentrated in Mosica and other advanced enterprises monopoly, equipment The price is generally more than 200,000.
