There are 7 types of plastic being circulated on the market that vary in their chemical composition, purpose, recyclability, and hazardous nature. 

1. Polyethylene terephthalate (PET, PETE)

This is the most commonly used plastic for mineral water bottles. The reason is probably the economy at the production stage, as well as the high recyclability of this plastic. In addition to mineral water bottles, PET is also often used as purified water bottles, cooking oil bottles, soft drinks bottles, juice bottles, sometimes dishwashing liquid bottles.

PET resin is chemically quite stable at room temperature however, at high temperature, PET is not stable and may give off some aldehydes and leach antimony. Should only be used for a short time (about less than 10 days) and then replace the new bottle. Do not use PET plastic for storing hot foods, or in the microwave.

2. High-density polyethylene, Low Density Polyethylene, Polypropylene

High-density polyethylene (HDPE), Low Density Polyethylene (LDPE), Polypropylene (PP) are three types of plastic with almost similar structure, only differing in physical strength.

• HDPE plastic is a plastic with a high density of polyethylene and is considered safe for food storage. HDPE resin has a high mechanical strength, is almost chemically inert, can withstand high temperatures (120 degrees C for a short time, or 110 degrees C for a long time). Therefore, HDPE plastic is often used as a baby bottle, medicine box, laundry detergent bottle, floor cleaner, bleach, shampoo, shower gel…However, for safe use, you should not discard it. microwave, avoid containing foods that are too hot (over 110 degrees C) or / and high in fat such as porridge, broth (broth) of vermicelli, noodles, and pho, unless they are specially designed for hot food storage.
• LDPE plastic is a plastic with a low density of polyethylene. It is often used to make plastic grocery bags, food wrapping paper…This is chemically inert plastic, but a bit less physical than HDPE, can withstand 95 degrees C in time short time, or 80 degrees C for the long time. Therefore, if choosing plastic food bags, LDPE plastic bags are also a good choice.
• Polypropylene (PP) is a plastic with a structure similar to two types of PE (LDPE and HDPE), and similar physical resistance and chemical inertness. The least durable PP has a melting point of about 130 degrees Celsius. Therefore, it is only suitable for storing foods up to about 110-120 degrees Celsius. PP plastic products are often found as specialized containers. food, plastic furniture, some kinds of plastic bags, plastic cups, plastic knives, plastic spoons…

 

3. Polyvinyl Chloride (PVC)

PVC is the third most widely used synthetic resin, after polyethylene and polypropylene. This versatile plastic can be either hard or flexible, depending on the additive added. It is commonly used in the manufacture of pill blisters, bed sheets, food-free bottles, cards (bank cards, chip cards), and the product of particular interest is baby toys and wrap, also known as glass bags, cellophane…Therefore, PVC is also considered as the plastic that should not be best for food.

4. Polystyrene

When combined with various colorants, additives or other plastics, polystyrene is used to make a variety of products including appliances, electronics, automobile parts, toys, gardening pots and equipment and more.

As a hard, solid plastic, it is often used in products that require clarity, such as food packaging and laboratory equipment.

Polystyrene also is made into a foam material, called expanded polystyrene (EPS) or extruded polystyrene (XPS), which is valued for its insulating and cushioning properties.

Food packaging contains substances that can “migrate” in very tiny amounts to foods or beverages. The FDA strictly regulates food packaging materials, including polystyrene, to be determine that the amount of substances that may migrate is safe.

5.Other plastics

Other types of plastic 6 types above are affixed with grade 7. In which, Polycarbonate plastic is the most concerned. This is the type of plastic commonly used to make water tanks (especially the 20-liter barrel), suitcases, phone cases, CD cases, plastic sheets…

Many studies show that bisphenol A, a constituent of this resin, is the most leaching-free hormone pseudo-hormone in the water contained in polycarbonates, however all of these leaching hormones, including bisphenol A, which are all below the US standard oral safe level. Therefore, to store food you should not use this material.

In short, to choose food-safe plastic, we should only use bottles bearing the symbols HDPE, LDPE, PP and PET. The remaining types of PS, PVC & other plastic (# 7) are not preferred when used as food containers.

GLOBAL TRADING  SUPPORT CO., LTD

2nd floor, Van Thanh office building – 602/27 Dien Bien Phu Street, Ward 22, Binh Thanh District, Ho Chi Minh City

Hotline: 0765.428.407 or Zalo : 0909628255 (Ms. Yen)

At Global Trading Support, our strength is to partner with many manufacturing factories in each field and provide high-quality products in a short period of time. The goods include mechanical steel, plastic products, clothing, stone, furniture, interior and exterior products, and convenient disposable products (rubber gloves, rubber bands, bamboo toothpicks, etc.). The factories are mainly in Vietnam, but in recent years we have been able to cooperate with factories in neighboring countries.

When looking for manufacturing partners, we always search for the latest data, visit factories to verify quality and negotiate properly, then choose the one that seems to be the best. From our point of view , determining whether large or small factories is not important to produce good products, but our target is to find a factory that can listen cooperatively, responds to strict requirements, and makes every effort to improve all the time. In order to reduce mistakes during production, we regularly inspect the products together with the factories for quality control. In addition, we are confident that we will deliver the goods quickly and safely by choosing a major top carrier!

By not only providing good products to customers, but also cooperating in the production of products that require high quality, the production capacity of each factory is increasing day by day.

* Mr. Trung, president of a company that specializes in processing steel products with which we have been working together for more than 10 years, said:

“In the beginning, we had a lot of defective products, so we sometimes wanted to give up, but thanks to the cooperation of GTS, we were able to overcome the difficulties.”

*Thanh, president of a cement pot factory in a suburbs of Ho Chi Minh City, said:

“The number of orders for pots from other companies has increased significantly compared to before. This is because partnering with GTS to make products that meet the Japanese quality standards helped me learn various experiences to improve my skills and make the products more beautiful. I really appreciate it.”
