Necessary knowledge about plastic containers

Plastic gallons or buckets are usually cheap containers that can be easily procured and purchased. All types of plastic bucket models have good strength and are widely used for domestic and industrial purposes.

Plastic container factories produce buckets in a variety of capacities and models, and the question may arise for many people whether it is possible to produce the desired capacity of the bucket or not. In fact, factories can change the capacity of the gallons and buckets according to the customer’s order, but it depends on the quantity of the order, which should be a noticeable number due to the costs and expenditures. 

People with home-based businesses and factory owners can order the capacity and model they want for the bucket and bucket factory, and then the relevant expert, after reviewing the order, will inform whether it is possible to produce the bucket with these specifications or not. In most cases, it is possible to produce barrels in various and desired capacities. In the following article, for more clarification, we will introduce you types of plastic bins, buckets, and gallons, plus their uses.

Types of plastic buckets

Plastic buckets are designed and produced according to the different needs of people in different sizes and shapes.  Besides different sizes, plastic buckets are available in both opaque and transparent types. Transparent plastic bins are produced in sizes of 0.5 liter to five liters, which have a thin, yet durable body. This type of plastic bucket is used to store food items such as pickles.

Plastic buckets are also different in terms of body thickness. In fact, the thickness of the body is evaluated according to the weight that the bucket is supposed to bear. Buckets are produced in different models of round, handle shape, flat, inserted, and with screw or simple doors and wire or metal handles which you can choose the desired model according to your needs.

Uses and applications of plastic containers

As mentioned above, plastic buckets are produced in various dimensions in opaque or transparent that each of them has a specific application. In the following, we have described some applications of different types of plastic buckets.

Application of small plastic buckets

Small plastic bottles are produced in the dimensions of one, two, four, or five liters, so by small plastic bottles, we mean those with the capacity of less than 5 liters. Small buckets are usually thinner and use less raw materials, so they are usually cheaper. These types of buckets are used in small businesses or for personal and more home use.

Small plastic containers are commonly used for packaging and storing foods such as yogurt, Iranian Dough, syrup, and milk. Other uses of this type of bucket include its use in the packaging of detergents such as handwashing liquid, dishwashing liquid, and even glue and paint.

Small plastic buckets are designed and manufactured in various models such as transparent buckets, lid buckets, etc.

Application of 10 liters plastic bucket

Ten-liter plastic bucket is one of the sizes that is widely produced and used in Iran. In fact, these bins are very versatile due to their desirable capacity, and on the other hand, they are easy to transport.

Ten-liter plastic bins are designed and produced in various models such as flat, round, with handle, three-line, two-line, wide-open bins, etc. Many home businesses or factories choose one of the models according to their needs for maintenance, packaging, and supply of their products.

Ten-liter plastic containers with high heights and small openings are used to store liquids such as vinegar, and models with larger openings are used for packaging pickles, pastes, dyes, etc.

In addition to the model, ten-liter plastic bins are also different in terms of the type and material of the handle. Some bins have plastic handles, and some have metal handles. Some plastic buckets, called armrests, have handles of the same material as the bucket.

Application of 20 liters plastic bucket

One of the most widely used containers for packaging is the 20-liter plastic container because it has a large storage capacity, and products up to 20 liters can be easily packaged and stored, so it is very popular in the packaging industry.

While these containers have a high storage capacity, they are very light and can be easily moved if they are empty, and this can be considered as one of the reasons for the popularity of these containers. 20-liter plastic buckets can be used for packaging chemicals and food, and also some kinds of buckets used to store household products such as yogurt and milk.

A 20-liter plastic bucket is also used to store various liquids such as fruit juice, water, gasoline, oil, chemical liquids. Due to the fact that these buckets have a high volume, therefore, liquids cannot be easily removed and used. The body of these buckets is …. so that the liquids inside it can be easily discharged, which is called a 20 liter … bucket.

Application of 100-liter plastic bin

100-liter plastic bins, or the same as plastic barrels, have more industrial use due to their high capacity. This size is made of a high-quality polyethylene plastic bucket and has high strength and durability. Consumption of 100-liter plastic containers can be mentioned for storage of drinking water and liquids, as well as for storage of products of the chemical industry, food industry, paint…. Is also used.

100-liter plastic barrels are produced and supplied in various types with rims, multi-layers with different doors, all of which affect the price of these barrels.

Everything you need to know about PET bottles

You may have heard of a pet bottle and want to know what a pet bottle is? And what are its uses? In this article, we provide complete information about PET bottles. If you want to have complete information about PET bottles, stay with us until the end of this article. Before you get acquainted with PET bottles, we will give a brief explanation about PET plastics.

What is PET plastic, and what are its uses

PET plastic is derived from the word Polyethylene Terephthalate. PET plastic belongs to the family of polyesters and is considered as a long-chain polymer.

PET plastic, which is a type of polymer, is made from two crude oil derivatives called modified ethylene glycol monomers and pure acid terephthalates. PET plastic is light, safe, and flexible, has a semi-crystalline appearance, and is also known as pure plastic due to its portability.

PET polymer is one of the most widely used polymers in the world, which is used to date in the following three industries:

Textile industry:

  1. Polymer PET is known in the textile industry as polyester. In the clothing industry, a type of pet called pet-p was used, but today it is no longer used, and its production has stopped.
  2. Packaging and food industry: PET plastic is used in the packaging industry as a moisture barrier. PET can be used in the production of soft drink bottles, mineral water, beverages, oil bottles, and even packaging of pharmaceutical, health, and cosmetic products. Pet polymer is known in the packaging industry as pet or pet resin.
  3. Engineering plastic: To increase the strength of various materials, this polymer is combined with other materials such as glass fiber.

What is a Pet Bottle

It can be said that PET is most widely used in the bottle packaging industry. The difference between PET bottles and other bottles made from different materials is that they are compatible with the human body, and no harm is done to the body by smelling or touching them. Other advantages of PET bottles include lightness and lightweight, resistance to the penetration of gases, cheapness towards glass and metals, high resistance to temperature, resistance to breakage, and their non-harmfulness. These are the reasons why the production and use of PET bottles are increasing day by day in the world. It is interesting to know that the highest percentage of recycled plastics in the world is made of PET bottles.


As mentioned above, PET bottles are widely used in the packaging industry. One of the most common uses of PET in the world is to make beverage bottles. But you should know that the decomposition of PET bottles takes 300 years, and this is one of the concerns of humanity, but due to the recyclability, this concern is partially resolved, and on the other hand, PET bottles, although light, occupy a large volume. Slowly

Types of pet bottles

Generally, PET bottles are produced in different types of medicated PET bottles, book PET bottles, 1 liter PET bottles, 5 liter PET bottles, cylindrical PET bottles, PET spice bottles, rose pet bottles, and dishwashing PET bottles, each with its own application. Have.

How to detect a pet bottle

Types of plastics are known by different signs. In fact, codes for plastics are internationally defined, which has a clear meaning for everyone, and the type of plastic can be identified by its code. The number 1, which is surrounded by three arrows, is engraved under the PET bottles, and through it, it can be understood that the material of the bottle is PET plastic.

Detection of recycled PET plastics

Recycled PET plastic is the most common type of recycled plastic and is known as RPET. Recycled PET plastic can be recycled into biodegradable bottles, carpet fibers, and wool.

Check for pet toxicity

PET plastic is biologically neutral and has no toxicity. This type of plastic is not dangerous for humans and their health if swallowed by humans or animals.

Advantages of using PET plastic

Low price of PET plastic: The main price of PET bottles and their types is much lower than the price of glass and metal bottles, so many companies and factories are replacing PET bottles with glass and metal bottles for packaging.

Ease of use: The lid of PET bottles can be easily opened and closed, and this is one of the simple advantages of using PET bottles.

The simple advantage is the use of PET bottles

Easy Recycling: About 30% of PET bottles are destroyed if left in the ground for two years, so it can be said that they have the characteristics of biodegradable plastics. So recycling PET bottles and turning them into other materials is a logical solution to this problem.

PET bottles are recycled in very large quantities, thus saving on the production of raw materials in the petrochemical industry. On the other hand, recycling PET plastics produces very few greenhouse gases and poses less of a threat to the environment.

High safety and health: In the preparation and production of PET plastics, materials such as non-metallic antimony oxide are used, and heavy metals are not used as catalysts so that they are not dangerous. This has led the Food and Drug Administration to give a safety rating to products made with PET plastic. These products do not threaten the health of producers and consumers.

How to recycle PET plastic

Pet plastic recycling process is done in the following steps:

PET bottles are collected and reduced to smaller particles. The purity of these particles plays an important role in the value of recycled plastics.

Using a particle separation technique that involves washing and sorting by airflow. At this stage, water baths are also used for classification, through which the fine particles either go under water or remain floating. In this way, various materials are also separated from the plastic.

At this stage, washing or heating methods are used to remove the contaminants, and then the particles are well rinsed so that the cleaning compounds or the remaining contaminants are well removed.

The recycled pet is dried to enter the next stage of recycling.

The plastics obtained from the previous steps are melted at the right temperature to separate the non-melting particles from them, and in this way, higher purity of PET plastic can be achieved.

What is a pleat? And ways to prevent it

Pleated or vomiting is the excess of plastic parts that result from the penetration of molten plastic into the seams between the male and female parts of the mold during the molding operation and, after the process, remains attached to the product.

If creasing occurs when the mold fills, reduce the filling pressure. And if creasing occurs when the mold is closed, reduce the holding pressure.

Ejection symptoms

Ejection marks are a depression of the part that is caused locally on the product by the forces coming from the ejection jack. Sometimes this depression is accompanied by tension.

Increase the number of pins. Reduce the power of the ejector jack as much as possible.

The fly jack operates quickly, and the piece is still hot.

The fly jack works late, and as a result, the piece shrinks more.

Uneven length of blade rods, which causes the piece not to come out of the mold properly, and too much pressure is applied to it.

Another type of problem is that the part is easily detached from the mold and falls on the machine tray, resulting in the part being crushed.
