A recent AMI company's declaration pointed out that by 2020, plastic heavy bags will account for nearly 60% of the market, spanning paper bags. The continuous improvement of plastic bag production techniques will further expand market share, such as the packaging of cement, food and pet food.
Heavy bag usually refers to a bag that can take 25kg of product. 2010 is the time point when plastic heavy bags crossed paper bags in number. After that, the share of plastic heavy bags has increased to nearly 55%, and it is estimated that by 2020, it will reach nearly 60%.
Plastic heavy-duty bags have a good "stacking ability", for example, compared with standing paper bags and woven bags , which can reduce storage space and lower transportation costs; plastic heavy-duty bags are lighter than the paper bags they replace, so they can significantly reduce the carbon footprint of packaging. .
In addition, compared to plastic-lined paper bags, plastic heavy-duty bags are 100% recyclable and have 100% sealing ability, so that dust-free disposal can be stopped without signs of overflow or splurge.
New sealing method is stronger
Some new techniques have appeared on the market in recent years. For example, Starlinger's IC * STAR bag adopts a new method of polypropylene (PP) bag sealing developed in conjunction with Statec Binder. plastic woven bag
Contrary to the sewing method, IC * STAR welds the sealing strip to the bottom of the bag through a hot atmosphere in a continuous process, without the need to apply an adhesive. The layout of IC * STAR also virtually eliminates the seam width required for sewing bags, and the strength of the bottom of the bag is higher, enabling the use of lighter weight fabrics. The combination of these two identities lowers the cost of raw materials (PP in this case) and reduces carbon footprint.
This method of sealing can make the bag completely sealed, which is its important strength. In addition, when the package is a fine powder product that easily passes through the pinhole to form dust, it will persecute health in some cases.
The oil-free panning process also makes it particularly suitable for packaging foods such as rice, coffee, salt, sugar or flour.
The plastic bag mouth is kept closed, and after active filling, it can be sealed or stitched with another sealing strip.
The IC * STAR bag is placed on the Starlinger bag multi-kON KX. This basin line is equipped with a seal TEC bottom sealing module developed by Starlinger and Statec Binder. The sealTEC module requires less protection than a sewing machine, and requires much less spare parts and consumables. Both coated and uncoated IC * STAR bags can adopt this new approach.
Promote at the rate
In terms of basin speed, Windmöller & Hölscher (W & H) pointed out that its new Conver Tex CL 140 machine now far exceeds the speed of all other heat seal bottom bags on the market. Since the first machine was put into production in July 2016, it is capable of continuous production 24 hours a day, and 140 65g PP cement bags are produced every minute.
Conver Tex heat-seals PP back-sealed bags, so adhesives are no longer necessary for such bags. In the past 10 years, the output of the sealing machine has more than doubled: from 60 bags per minute to 140 bottles per minute.
Adopting new techniques can turn lighter plastics into high-quality bags. plastic woven bag
This new technique from Weidhall is called LS (Lighter & Stronger), a high-quality PP film with a toughness of up to 7g / den, plus the indexing micro-perforation technique, which can reduce 15g or 20% when the 65g cement bag is used. Of weight.
