About Qiming Packaging Plastic Buckets

A.Qiming Packaging Production Process

The plastic raw material granules are added to the injection molding machine, and the plastic is melted by high-temperature high-pressure injection into the steel mold through the heating of the cylinder. After cooling, the mold is opened and the product is taken out, and the finished product is obtained by trimming the burrs.

Different sizes of the Plastic Round Buckets

Every day, people use plastics in various applications. Over the last 50 to 60 years, the uses for plastic have expanded to infiltrate virtually every aspect of life. Because of how versatile the material is, and how affordable it can be, it has taken the place of other products including wood and metals.

The properties of the various types of plastics make it beneficial for manufacturers to use. Consumers like it because it is easy to use, lightweight and easy to maintains.

Types of Plastics

Overall, there are about 45 unique types of plastics and each type has dozens of different variations. Manufacturers can change the physical structure just slightly to benefit the application for which they are using it. When manufacturers change or modify things like the molecular weight distribution, the density of the melt indices, they alter the effectiveness and create plastics with many specific properties – and therefore many different uses.

Two Plastic Categories

There are two main types of plastics, thermoset plastics and thermoplastics. Breaking these down further, you can see the everyday uses of each type. With thermoset plastics, the plastic will hold its shape long term once it has cooled to room temperature and hardened thoroughly.

This type of plastic cannot return to its original form – it cannot be melted down into its original form. Epoxy resins and polyurethanes are some examples of this type of thermosetting plastic. It is commonly used in tires, auto parts, and composites.

The second category is thermoplastics. Here, you have more flexibility and versatility. Because it will return to its original form when heated, these plastics are commonly used in various applications. They can be made into films, fibers, and other forms.

Specific Types of Plastics

Below are some of the specific types of plastics and how they are in use today. Consider their chemical properties and benefits, too:

PET or Polyethylene terephthalate – This plastic is ideal for food storage and water bottles. It is commonly used for things like storage bags, too. It does not leach into the food, but is sturdy and can be drawn into fibers or films

• 

• 

• 

PVC or Polyvinyl Chloride – It is brittle but stabilizers are added to it. This makes it a softer plastic that’s easy to mold into various shapes. It is commonly used in plumbing applications because of its durability.

• 

• 

• 

Polystyrene – Commonly known as Styrofoam, it is one of the less ideal options today for environmental reasons. However, it is very lightweight, easy to mold and it works as an insulator. That is why it is heavily used in furniture, cabinetry, glasses, and other impact-resistant surfaces. It is also commonly added with a blowing agent to create foam insulation.

Some of the chemical components in plastics are believed to affect the development and reproduction of animals. Their waste fills the earth, and those chemical components eventually penetrate into the groundwater; plastic waste is thrown into the ocean, and some animals swallow it. That is sad!

However, there is always another side of the balance. Plastics also have benefits, not only economic but also environmental.
Cars made of plastic parts are lighter and consume less fuel; plastic packaging prolongs food preservation time and reduces waste; if the bottle is not plastic, it must be glass. What kind of broken bottle do you want to see in the amusement park where children go to play?

In the end, we must improve the recycling and reuse of plastics, even if it is because crude oil is not used.

Some plastics cannot be recycled, such as bakelite, but many that can be recycled are still not recycled. In fact, the recycling rate of plastic packaging is only about one-seventh, far less than paper and steel. The recovery rate of other plastic products is even worse.

Improvement requires everyone to work hard. As you may have seen, some plastic products now have a small triangle with numbers 1 to 7. That is the “resin identification code”, which is an initiative of the Plastics Industry Association to help recycle. But this system is far from perfect.

If the industry can make more efforts, the government can. At present, the recycling rates of plastics in various countries and regions vary greatly. However, a very successful example is Taiwan.

The measures taken by Taiwan have made recycling more convenient and the offenders face fines, successfully challenging the traditional attitude of people dealing with garbage.
So, is there any other technical method for managing plastic waste? People who love science fiction must love a recently new invention: ProtoCycler. Give it plastic waste, it will spit out 3D printed wire! Moreover, all Qiming packaging plastic products’ material can be recycled.

1. About PVC and PE

What is PVC?

Polyvinyl chloride is a polymer of vinyl chloride monomer (VCM) in the presence of an initiator such as a peroxide or an azo compound; or a polymerization mechanism under the action of light or heat. The vinyl chloride homopolymer and the vinyl chloride copolymer are collectively referred to as vinyl chloride resins.

PVC is a white powder with an amorphous structure, with a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77-90 ° C, and decomposition at about 170 ° C. The stability to light and heat is poor, above 100 ° C or over a long period of time. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalytic decomposition, causing discoloration, and physical and mechanical properties are also rapidly declining. In practical applications, stabilizers must be added to improve the stability to heat and light.

Industrial production of PVC molecular weight is generally in the range of 50,000 to 110,000, with greater polydispersity, molecular weight increases with the decrease of polymerization temperature; no fixed melting point, 80-85 ° C begins to soften, 130 ° C becomes viscoelastic state, 160 ~ 180 ° C began to transform into a viscous flow state; has good mechanical properties, tensile strength of about 60MPa, impact strength of 5 ~ 10kJ / m2; has excellent dielectric properties.

2. Main differences-Difference Between PVC and PE

A.The difference in an application:

Polyethylene (PE) applications: plastic wrap, vest plastic bags, plastic food bags, buckets, kettles, etc.

Polyvinyl chloride (PVC) applications: plastic wrap, plastic shoes and leather products, film, cable, plastic bags.

B.Different characteristics:

Polyethylene (PE) has a waxy feel and is lighter in weight and has certain transparency compared to the same plastic.

Polyvinyl chloride (PVC) characteristics: hard plastic, commonly used in industrial fields.

C.Material performance difference:

Polyethylene referred to as PE. It is a polymer of ethylene and is non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, electrical insulation. It is suitable for packaging materials for food and medicine, making utensils, medical equipment, and insulating materials for the electronics industry.

Polyvinyl chloride, referred to as PVC. It is a polymer of vinyl chloride. Polyvinyl chloride (PVC) is a synthetic material with many advantages and is an ideal material for engineering plastics. Good chemical stability, acid, and alkali resistance. Resistant to moisture, aging and flame retardant.

Polyvinyl chloride, English abbreviation PVC (Polyvinyl chloride), the original color is the yellowish translucent, shiny, relative density of about 1.4. Transparency is better than polyethylene and polypropylene. The hardness of hard products is higher than that of low-density polyethylene but lower than that of polypropylene. It is not easily corroded by acid and alkali and is more resistant to heat. Polyvinyl chloride has the advantages of high flame retardancy, high chemical resistance, good mechanical strength, and electrical insulation.

PVC polyvinyl chloride has poor stability to light and heat. Without heating the stabilizer, the polyvinyl chloride starts to decompose at 100 ° C and decomposes faster at 130 ° C or higher. It is decomposed by heat to release hydrogen chloride gas to discolor it, from white to light yellow → red → brown → black. The ultraviolet rays and oxygen in the sunlight cause photo-oxidative decomposition of the polyvinyl chloride, thereby lowering the flexibility of the polyvinyl chloride and finally becoming brittle. Therefore, some PVC plastics will turn yellow and become brittle after a long time.

PVC is widely used for pipe, general injection molding molds, packaging materials, blow-molded transparent packaging materials, etc.

For example, in our daily life, we see packaging products, PVC fruit trays, egg trays, and packaging boxes in supermarkets or stores.

2. Available sizes to meet the different needs of the customers.

Everyone should know that many of the pet products are made of plastic. For example, pet food covers and PET jars (refer to the picture like below). But, do you know how to choose more safety plastic products for pets? Here I have some suggestions and recommendations for your reference. Contact us!

1. Material

The material of high-quality plastics are PVC or PE materials, and all plastic products for pets should be food-grade, non-polluting, and recyclable. Our products meet all of the above features.

2. Look at the gloss and production process of plastic products

 PVC plastic itself is very shiny and many of the inferior plastic products are recycled and processed from waste plastic products. In addition, our PET jar is made by automatic machine, no hand touching in production to increase the efficiency of production, the mold and product are clearly visible and high quality.

And our pet food can lids are also food grade PE material,they could isolation odor,endure high temperatures,it’s hard,not easy to distort.
