Classification and packaging types of pesticide plastic flexible packaging

Water, Emulsion, Powder

Pesticide symbols on pesticide packaging and pesticide instruction manuals are generally composed of one to three letters of the alphabet, some representing pesticide dosage forms, and some representing pesticide measurement and concentration.

In terms of pesticide formulations, “EC” means emulsifiable concentrate, the most common pesticide symbols, such as “Lego” 40EC means the content of 40% of the Lego emulsifiable concentrate; “OL” means oil. OL” means oil, such as ‘Likonin OL’ that is, Likonin oil; ‘ES’ means emulsion, emulsion, emulsion, emulsion; ‘WG’ means water dispersible granules; ‘WG’ means water dispersible granules; ‘WG’ means water dispersible granules; ‘WG’ means water dispersible granules; ‘WG’ means water dispersible granules; ‘WG’ means water dispersible granules. “LS” indicates that the seed treatment solution.

Pesticide plastic flexible packaging requirements for adhesives, as well as adhesives in the application of pesticide plastic flexible packaging, adhesives need to have what performance, characteristics and technical parameters:

Flexible packaging manufacturers to cope with the strategy

The future development of pesticides will be highly efficient direction, the form of pesticide product development will also tend to be highly efficient, low dosage of liquid pesticides. However, the current market of pesticides in the form of plastic packaging, especially liquid pesticides (emulsifiable oil-based) using plastic bags in the form of packaging is not common. The key reason is that most of the pesticides contain toluene, xylene and other highly permeable organic solvents, ordinary composite films and adhesives are easy to react with organic solvents in pesticides, resulting in packaging materials, delamination, dissolution, resulting in leakage phenomenon. Pesticides are a toxic and dangerous goods, their packaging there are many safety hazards:

First, there are small packages, such as low-toxicity herbicides, its packaging materials, size, color and children's yogurt, calcium milk packaging is extremely similar, there have been reports of children accidentally eaten and lost their lives. In this regard, manufacturers should immediately change the packaging design, so that it has a clear warning signs and differentiate the appearance of common food packaging.

Secondly, the design of pesticide plastic bags should be improved, both to ensure the safety of the plastic bag strength, but also marked the location of the opening, so that users can tear open, to avoid strong tearing, biting and other insecurity factors.

Third, large packages of pesticides sold in small packages or bulk is conducive to the actual needs of farmers, but how to ensure that small packages of labels and instructions, to prevent improper adulteration, to prevent pesticide volatilization caused by accidents is whether the dealer is the strict implementation of the State “Pesticide Management Regulations” of professional ethics;.

Fourth, a large number of pesticide packaging waste is casually discarded in the riverside, field, ground, both contaminated soil, water, but also contaminated agricultural products, some people do not know the pesticide packaging and even take the packaging of other items, resulting in harm. To strengthen publicity, tips farmers do not throw pesticide packaging, manufacturers should also take the initiative to recycle pesticide packaging, not only the use of safety, but also comprehensive utilization to reduce production costs.

Pesticide Industry Association of China, Wang Ruixian, chairman, pointed out that: in the pesticide plastic bag packaging, how to solve the problem of static electricity generated by the packaging of powder pesticides, is one of the current urgent need to solve the problem. Pesticide powder in the filling is easy due to static electricity to fly out, so that the sealing quality is affected, resulting in poor sealing of the package. The convenience of pesticide packaging has become one of the user's attention to one of the goals, small bag packaging, economic, convenient, there are 10g-20g packaging. Pesticide products also have the use of metal packaging, metal to aluminum-based, but the cost of aluminum is very high, can not be universally used.
