Plastic buckets have significantly better performance than traditional types of containers such as fiberglass containers, plastic welded containers, and steel lined rubber containers. It has a wide range of applications and can not only replace metal containers such as stainless steel and titanium, but also be an ideal choice for the storage and transportation of chemical liquids today. Plastic buckets are not only durable, but also affordable, suitable for multiple industries such as chemical, dye, metallurgy, rare earth, machinery, electronics, environmental protection, textile, and food. In addition, according to different needs, there are various specifications of plastic chemical drums available on the market, such as 5L, HDPE 200kg plastic drums, 10L, 15L, etc., to meet the storage and transportation needs of different industries.   Plastic buckets are widely used in Shandong region, with a wide variety of types including ton buckets, square buckets, toilet stacks, and flanged buckets. At the same time, the specifications of these plastic buckets also vary, which can meet different needs. Next, we will introduce these common types of plastic buckets one by one.   1. IBC ton drum   The capacity is 1000 liters, designed specifically for the storage and transportation of bulk liquids.   2. Square bucket series   Including capacities ranging from 2L to 100 liters, meeting various small capacity liquid storage needs.   3.

What are the requirements for qualified packaging drums?   Because we usually use packaging drums and there are no major problems during use, we are not familiar with their various quality standards. However, this may hide some issues. Therefore, when purchasing, we need to understand what standard requirements qualified packaging drums must meet.   Packaging drums have high requirements for heat and cold resistance, and will not deform in high-temperature water.   Durable packaging barrel: It should have superior impact resistance and be not easily broken under heavy pressure or impact.   Packaging bucket sealing: This is the primary consideration when choosing a takeaway bucket. Although different brands have different sealing methods for their products, sealing is a necessary condition for the preservation of stored food.   Packaging bucket preservation: The upper sealing test standard is evaluated based on moisture permeability testing. The moisture permeability of the preservation bucket is 200 times lower than that of similar products, which can keep things fresh for a longer time.   When purchasing packaging drums, one can also consider their environmental characteristics, as odorless and UV resistant packaging drums can meet any usage requirements in our daily lives.   I hope the above content can help everyone better understand packaging drums. If there is anything else you don't know, you can directly communicate with our customer service. We are dedicated to serving you. Thank you for watching.

Chemical plastic drums are widely used in various places, and their appearance has brought us great benefits. So how should we store them? Below, the editor will briefly introduce its related knowledge points to everyone.   1. It is necessary to ensure that the packaging and sealing of dangerous goods are firm after filling, and the heat sealing of the plastic bags inside the plastic drums must be good or firmly tied, without any leakage or spillage.   2. If the filled product is prone to produce volatile gases, especially in February, April, and August when the temperature difference effect is significant, it should be filled at a lower temperature time of the day to avoid concave and deformed images.   3. When loading hazardous materials into chemical plastic drums, the outer surface of the drums must not be corroded or damaged, and the appearance must be clean and in good condition.   4. The individual weight or volume of hazardous materials contained in chemical plastic drums shall not exceed the higher limit specified in the regulations for the transportation of hazardous materials.   5. It should be stored under a canopy to avoid exposure to sunlight. The higher usage temperature is 60 ℃, and the storage temperature should be below 40 ℃. The shelf life is 1 year from the date of production.   The above are the relevant knowledge points of chemical plastic barrels. We hope that the above content can be helpful to everyone. Thank you for watching and supporting, and welcome everyone to cooperate with us.

Plastic is currently a widely used packaging product in the market. Today, we will mainly talk about plastic coating buckets, which can effectively encapsulate coatings and have good sealing properties. Of course, in today's market, there is a mix of good and bad, and there are also some paint buckets with poor sealing. So, what are the factors that affect the sealing of plastic paint buckets? There are four main factors that affect the sealing performance of plastic coating buckets:   Firstly, the plastic material is of poor quality. Usually, some manufacturers mix waste materials to reduce product costs, resulting in a decrease in raw material quality and affecting the sealing of the bucket. Of course, some customers do not have high requirements for the sealing of paint buckets and use new materials for production, which is another matter.   Secondly, the ingredient formula is not professional. There are various materials used in the production of plastic buckets, including polyethylene and polypropylene. Due to the different plastics and additives used in the production of plastic buckets, and the significant differences in the properties of different raw materials, some materials are harder and some are softer. To improve the sealing performance of paint buckets, it is necessary to fully understand the material properties and give full play to their advantages. The proportion and formula of materials are crucial, as they are important factors affecting the sealing performance of paint buckets.

Storage purpose: Food storage edible oil: Plastic barrels are often used to store edible oils such as peanut oil, rapeseed oil, etc. For example, some small plastic oil drums have capacities ranging from a few liters to over ten liters, making it convenient for families to purchase an appropriate amount of edible oil. They usually have good sealing properties, which can prevent oil oxidation and the entry of external dust and debris, extending the shelf life of edible oil. Seasoning: Seasoning such as soy sauce and vinegar can also be packaged in plastic barrels. These plastic buckets are generally designed in a shape that is easy to pour, and the surface will have anti slip design, making it convenient for people to use in the kitchen. Chemical Storage Industrial Chemicals: In the chemical industry, plastic drums are used to store various chemicals, such as corrosive liquids like acids and alkalis. For example, strong corrosive chemicals such as sulfuric acid and sodium hydroxide can be stored in corrosion-resistant plastic drums (such as polyethylene drums), which can effectively prevent the corrosion of containers by chemicals and also avoid the harm of chemical leaks to the environment and human health. Pesticides: The packaging of pesticides also relies on plastic barrels. Like some insecticides, herbicides, etc., plastic barrels can withstand the chemical properties of pesticides and are convenient for transportation and storage. These plastic buckets usually have strict sealing measures to prevent pesticide volatilization and leakage.   Body storage water: In some remote areas or temporary water use scenarios, plastic buckets are used to store drinking water. For example, some outdoor enthusiasts use plastic buckets to store clean drinking water for easy use in the wild. These plastic buckets are usually certified for food safety to ensure that the water quality is not contaminated. Fuel: In some small gas stations or remote areas, plastic barrels are used to store fuels such as gasoline and diesel. They have good sealing and oil resistance, which can prevent fuel evaporation and leakage, and are convenient for handling and storage.
