Plastic heavy duty bags or 60% market share in the plastic bag industry

Plastic heavy duty bags generally refer to bags that can hold 25kg of product. It is reported that plastic heavy bags in 2020 will probably account for nearly 60% of the market, exceeding paper bags. Plastic bag production technology is constantly evolving and will further expand market share, such as food and pet food packaging bags.
In 2010, the number of plastic heavy bags exceeded the number of paper bags. Since then, the share of plastic heavy bags has increased to nearly 55%. Plastic heavy-duty bags have better “stacking capacity”. For example, compared with upright paper bags and woven bags, storage space can be reduced and transportation costs can be reduced. Plastic heavy-duty bags are lighter than the paper bags replaced, thus significantly reducing the carbon footprint of the package. . In addition, the plastic heavy-duty bag is 100% recyclable and has a 100% sealing capacity compared to a paper bag covered with a plastic liner, so that dust-free treatment can be performed without waste.
The new method of sealing bags is more powerful
Some new technologies have appeared on the market in recent years. For example, Starlinger's IC*STAR bag uses a new method of sealing polypropylene (PP) bags developed in conjunction with Statec Binder.
Unlike the sewing method, IC*STAR welds the sealing strip to the bottom of the bag by hot air in a continuous process without the use of an adhesive. The structure of the IC*STAR also virtually eliminates the seam width required to sew the bag, and the bottom of the bag is stronger and a lighter weight fabric can be used. The combination of these two factors reduces the cost of raw materials (PP in this case) and reduces the carbon footprint. This method of sealing allows the bag to be completely sealed, which is an important advantage, especially in packaging fine powder products that easily form dust through the pinholes, and in some cases can be hazardous to health. The oil-free production process also makes it particularly suitable for packaging foods such as rice, coffee, salt, sugar or flour.
The plastic bag opening is kept open and, after automatic filling, can be sealed or stitched with another sealing strip.
Increase production speed
In terms of production speed, Windmall (Hellshall & H?lscher, W&H) pointed out that its new Co nver Tex CL 140 machine now far exceeds the speed of the bottom sealer of all other heat-sealed bags on the market. Since the first machine was put into production in July 2016, it can be produced continuously for 24 hours every day, and 140 65gPP cement bags are produced every minute. Co nver Tex heat seals PP backing bags, so these bags no longer require the use of adhesives. In the past 10 years, the production of the backing machine has more than doubled: from 60 bags per minute to 140 per minute.
New technology can be used to process lighter plastics into high quality bags.
This new technology from Wedhall is called LS (Lighter & Stronger), high-quality PP film with a toughness of up to 7g/den, plus indexing micro-perforation technology, which can reduce 15g or 20 when producing cement bags weighing 65g. %the weight of.

Lathe parts processing

Lathe parts processing refers to the manufacturing process of creating custom metal parts on a lathe machine. Lathe machine is a versatile tool used in various industries including automotive, aerospace, and electronics. Lathe parts processing involves using a lathe machine to cut, shape, and form metal parts according to the required specifications.


The process of lathe parts processing involves several steps. First, the metal material is selected based on the specific requirements of the part to be produced. Once the material is chosen, it is loaded onto the lathe machine, and the cutting process begins. The lathe machine is programmed to move the material towards the cutting tool, which removes material to create the desired shape and dimensions.


Lathe parts processing can produce a wide range of parts in varying shapes and sizes. Lathe machines use a variety of cutting tools, including drills, taps, and reamers, to produce parts according to the required specifications. Additionally, the lathe can produce components with varying levels of complexity, from simple cylindrical shapes to more complex shapes with intricate details.


One of the significant advantages of lathe parts processing is its ability to produce large quantities of parts with high accuracy and consistency. Lathe machines can be programmed to produce the same part repeatedly, ensuring consistency and quality control. This is especially beneficial in industries where a large volume of identical parts is required.


Another advantage of lathe parts processing is its versatility. Lathe machines can be used to produce parts from a variety of materials, including metals, plastics, and composites. Additionally, lathe machines can produce parts with various finishes, such as polished or textured surfaces.


In conclusion, lathe parts processing is an essential manufacturing process in various industries. It offers the ability to produce customized parts with high accuracy and consistency, which is vital in industries where quality and precision are critical. With the ability to produce parts in large quantities, lathe parts processing offers a powerful solution for a wide range of applications.
