Chemical packaging is another type of packaging that is quite in demand in the packaging industry nowadays. It includes modern methods and techniques of packaging that are very feasible in providing quality products to customers.
In chemicals, there are different varieties of chemical particles and powders are used. The packaging of such products requires a lot of cautiousness. Hence, packaging should be taken place in the best possible way. In this article, we will talk about different packaging techniques, which are the best ways of doing it, but first, let’s talk about the most important chemical products.
Common Chemical Products Used In Industry
In industries, chemical particles and chemical powder additives are very common raw materials used in different products. Here, we are highlighting some of the chemicals which are present in various forms. Example; plastic particles, rubber particles, PVC particles, polyester resin, epoxy resin, phenolic resin, color masterbatch, curing agent, titanium dioxide, ammonium sulfate, glycolic acid, polymer activated carbon, bentonite, Kester, silane coupling agent, nitrile rubber powder, zinc stearate, and p-cyanophenol.
Below, we are classifying some of the chemicals separately to get a better idea of their traits.
- Polyvinyl chloride (PVC)
- Polyethylene has different density levels used in different products. The ranges of densities are; low density (LDPE), high density (HDPE), low linear density (LLDPE).
- Cross-linked polyvinyl chloride (XLPVC)
- Polypropylene (PP)
- Cross-linked polyethylene. Some of its materials are; peroxide cross-linking material, silane cross-linking material, radiation cross-linking material (XLPE)
- Low-smoke halogen-free polyolefin (DWPJ)
- Low-smoke and low-halogen polyolefin (DDPJ)
- Poly tetra fluoro ethylene (PTFE/F-4)
- Pokyfluoroethylene propylene (FEP/F-46)
- Polyimide (PI)
- Polyamide (PA6)
Rubbers are also included in the types of chemical products. Hence, we are mentioning some of its major materials.
- Natural (styrene-butadiene) rubber (NR)
- Ethylene propylene rubber (EPR)
- Silicone rubber (SIR)
- Chloroprene rubber (CR)
- Chlorosulfonated polyethylene (CSPE)
- Polyvinyl chloride-Nitrile compound (PVC-NBR)
- We have different types of resin like; phenolic resin, polyester resin, polyamide resin, alkyd resin, acrylic resin, synthetic fatty acid resin.
Moreover, Some liquid chemicals are widely used in some industries, such as Alum, Cadmium cyanide, Hydrochloric acid, Lithium, Phosphoric acid, Phosphorous, Soda ssh, Sodium chloride, and more.
How to Store Chemical Products?
Chemical material exists in particle form, so we need such kind of packaging that restores it safely. In this regard, bag packaging out of all is considered as the best way to pack them. It is an ideal packaging container that is best for powdered and granular products.
The bag can package products like fertilizers, pesticides, cement, grains, etc. Bag packaging has a range of 20kg-50kg products that are reliable for loading and unloading, stacking, and handling. The best thing is it is an ideal and appropriate option for storage.
Common Bag Types of Chemical Packaging
In the category of bag packaging, numerous types of packaging are available, which is feasible according to the type of product. Below, we will present four types of bag packaging that are considered the best packaging of chemical products and powders.
- Plastic Woven Bag
Plastic woven bags have amazing benefits, including a high strength to hold the product in it, aging resistance, resists moistures, is a non-toxic bag, does not cause tastelessness, and are very affordable.
It is the most common, trusted, and reliable packaging ideal for chemical products. Hence, many people prefer plastic woven bags for packaging.
- Craft Paper Bag
Craft paper bags are also used for chemical packaging. It is leak-proof, which means save the product in the package. It can also prevent moisture from reaching the package. The product will be breathable. Craft paper bag is anti-static and non-slip too.
- Plastic And Paper Compound Bag
They are paper-cloth mixed bags and have an inner plastic lining of propylene, made up of (PP bag with PE lining). PP polypropylene is a thermoplastic resin, a polymer of propylene. They are considered very hard in nature, and that’s why they used to make castings and fibers.
PE polyethylene is a polymerized vinyl resin. We use it in containers, kitchen utensils, tubes, and in the form of rolls and sheets for packaging.
- Jumbo Bag
Jumbo bags are very large containers sued for packaging chemicals. They are medium-sized bulk containers. The characteristics of jumbo are; have large volume, light in weight, easy to load and unload. Jumbo bags are the most common type of transportation bag.
Jumbo bags are mostly used for the packaging of powder and granular products. It is also used for bulk goods like; chemical products, mineral products, agricultural and sideline products, cement, pesticides, etc.
These bags have a capacity of 400kg-3000kg of filling products in them. They are also found in different shapes like; round C-shaped and square S-shaped. It is made up of woven plastic processing and sewing. It is an ideal packaging for lifting transportation tools. It can be easily loaded and unloaded.
How To Choose Chemical Packing Machines?
The variation in packaging machines is due to the type of product and package you are using. Every product has some distinct features, and that’s why they require a special type of package in which they can be packed. Due to the reasons, we have different types of packaging machines.
It depends upon the weight of the package. The packaging weight of chemical raw is generally between 10-15kg. As we have mentioned four types of packaging in the previous section, we are now discussing four types of machines used for packaging raw materials.
- Open Mouth Bagging Machine
The open-mouth bagging machines are designed for free-flowing materials into open-mouth bags. It can fill products in packages between 5 and 50kg per bag. This machine has advanced systems of operation, which are ideal for bagging flakes and granules of food. They are ideal for foods like; feed, pet food, chemicals, and minerals.
- Bottom-up Filler
Bottom-up filler machines are best to ensure high accuracy during the filling process due to bottom-up filling technology. We first place a bag for filling, and after that filling, the spout moves down the bag during the filling cycle. Having less distance between the filling point and the product in the bag helps minimize the dust emission and reduces the product aeration.
The vertical screw controls this process and allows powdery products to be filled with total hygiene and clarity. This process is very important and hence done with accuracy. Bottom-up filler has a bagging system which is a cost-effective design. It includes bag transport with open-bag top transport or bag transport with closed bag-top.
- FFS Bagging Machine
FFS bagging machine has a film bag, and it is an automatic machine. It divides the cylindrical film roll into individual open-mouth bags and performs the function of bagging. It seals the heat when finished product output.
- Jumbo Bagging Machine
One of the best packaging machines that enhances packaging precision is convenient for checking and maintaining the quality of the product in the package. This bagging machine uses an 8-10mm steel plate with a laser riveting assembly technology to make the structure finer and table.
The automatic blowing bag system avoids manual operation, and hence it increases the production by a great amount. It has a dust extraction component that is automatically controlled by PLC, which guarantees no dust leak during the filling of the package. It is environment-friendly and keeps it clean with good air.
Chemical packing requires such techniques and methods where we need to pack it carefully. The best way of packaging chemical products is to choose the bag option, like paper woven bag, jumbo pack, and craft paper bag.
After choosing the bag, the next important thing is to use the ideal machine that has been specifically designed for it. Analyze the situation carefully and then go for the right and best option.
