German Henkel first invented washing powder in 1907 with borate and silicate as the main raw materials first. Washing powder is an alkaline synthetic detergent. The main ingredients of washing powder are anionic surfactants: sodium alkyl benzene sulfonate, a small amount of non-ionic surfactants,add some additives, phosphates, silicates, Yuan ming powder, fluorescent agent, enzyme, etc. It is made by mixing, dusting and other processes. 4A fluorspar is now mostly used instead of phosphate.
After the 1940s, with the development of the chemical industry, people used sodium tetrapropylene benzene sulfonate, a chemical substance extracted from petroleum, to manufacture detergents with better performance than soap. Later, people added phosphates, which can soften hard water and improve the decontamination effect of detergents, into detergents, so that the performance of detergents is more perfect. For the convenience of use, carrying, storage, and transportation, people make detergents into washing powders.
Because washing powder can show good decontamination effect in various water quality such as well water, river water, tap water, spring water, and even sea water, and is widely used in various fabrics, its production and use have developed rapidly. Now, washing powder is almost a necessary washing item for every household.
The washing powder packaging machine is a packaging machine that quantitatively divides the mass-produced washing powder into bags of washing powder that meet the market requirements.

The application and development of packaging bags for washing powder has gone through a process from simple to complex.
In the 1970s and 1980s, PE bags were printed in 1-2 colors, and in the mid-1990s, they developed into composite bags printed in 1-6 colors. Bags, and choose different materials according to the content, such as ordinary powder use BOPP/PE structure, ultra-concentrated powder use PET/PE structure, in the late 1990s, due to large specifications (such as 2kg, 3kg, 5kg, etc.) Appeared, higher requirements were put forward for materials, and BOPA/PE structure with higher strength was selected.
With the development of printing and plate-making technology and the emergence of many new high-barrier and high-strength materials, the development of washing powder packaging bags has shown a wider space. At present, bag printing can reach up to 12 colors, PVDC, PT, vacuum aluminum plating New materials such as film (VM) have also been researched and used, and laundry powder packaging bags are developing in a more practical and beautiful direction.
The quality requirements of Liby washing powder packaging bags are as follows: Appearance quality of composite bags:
Printing: Specific requirements are put forward for pattern content, hue, overprinting, and anti-counterfeiting signs. For example, overprinting requires color and color overprinting error, the main view surface is ≤ 0.2mm, and the non-main view surface is ≤ 0.3mm.
Bag making: specific requirements are put forward for compounding, size, thickness, heat sealing requirements, easy tear opening, wrist hole, cutting bag, etc. For example, the thickness control stipulates that the total thickness of the bag/film is less than 100μm, and standard deviations are allowed. The total thickness of the film is more than 100μm, and the allowable deviation requirements, etc.
Physical and chemical properties of composite bag:
There are 6 main aspects: heat sealing strength, composite strength, wrist strength, pressure test, drop test. Such as heat sealing strength: according to different materials, the average value is controlled at 21N/15mm - 35N/15mm. Film breaking force and breaking elongation: According to different materials, breaking force, transverse and longitudinal elongation are required. Composite strength: According to different materials, the average value is controlled at 1. 8N/15mm - 3. 0N/ 15mm. Under normal storage conditions, there will be no separation or blistering within two years. Stable drop test under high and low temperature conditions: 1.5mm - 2mm, 12 drops, no powder leakage occurs.
