PET821 Polyethylene Terephthalate; Bottle Grade

 

Introduction

PET821 is one of the most widely used grades of polyethylene terephthalate in the packaging industry, specifically designed for the production of mineral water bottles, carbonated drinks, edible oil bottles, and pharmaceutical containers such as pill and medicine cans. This grade has found a special place in domestic and export production lines due to its good balance between transparency, mechanical strength, chemical resistance, and high processability.
In a situation where manufacturers are faced with challenges such as reducing bottle weight, increasing productivity, maintaining appearance quality, and meeting health standards, PET821 can be a suitable answer to these needs. Simultaneous access to Iranian grade for domestic sales and foreign grade with delivery from Jebel Ali for export has made this product a flexible option for regional and international markets.

Product Description

Polyethylene terephthalate is a type of polymer that is used in most countries to produce polyester fibers (70%), bottle resin (22%), film (6%), and engineering polyester resins (2%), but in Iran this polymer is mostly used to make various types of beverage bottles.

PET is the most widely used thermoplastic polymer in the world. In the textile industry, this polymer is known by the trade name polyester. PET is naturally transparent and is considered a semi-crystalline plastic.

Polyethylene terephthalate (BG821) (BG820S) or BG821 material is a bottle grade polyethylene terephthalate (PET) produced by a continuous melt polymerization process combined with solid state polymerization. This polymer grade has very good transparency and gloss, high toughness, and is highly resistant to oxygen and carbon dioxide penetration.

Features

Very good transparency and gloss, high toughness, and is highly resistant to oxygen and carbon dioxide penetration.

High optical clarity
PET821 allows the production of bottles with high transparency and a crystalline appearance, which is very important for beverage and mineral water brands. This feature helps to better see the final product on the shelf.
Good mechanical strength
This grade has a good balance between tensile strength and impact resistance, so that the bottles do not deform or crack under the pressure of carbonated beverages and the stresses of transportation. They do not crack.
Stable processability
PET821 behaves uniformly in preform injection lines and shows little fluctuation in the process. This reduces waste, increases production speed and stabilizes the quality of the final product.
Chemical and hygienic resistance
This grade is resistant to oils, weak acids and compounds found in beverages and is compatible with food and pharmaceutical contact standards.

Applications

The applications of PET821 polyethylene terephthalate are in carbonated beverage bottles.

PET 821 is used in various industries due to its technical characteristics, including:
• Production of mineral water bottles in different volumes

 

• Carbonated beverage bottles with high internal pressure

• Bottle of cooking oils

• Pharmaceutical containers such as pill bottles, syrups, and supplements

 

• Transparent packaging for appearance and hygiene sensitive products

This variety of applications has made PET 821 an economical and technical choice for manufacturers.

Advantages

• Possibility of lightening the bottle without compromising quality
• Reducing production waste and increasing line efficiency
• Maintaining the taste and quality of the contents inside the bottle
• Compatibility with export markets such as Pakistan, Afghanistan, Iraq, Turkey, Russia and the Gulf countries
• Simultaneous access to domestic and foreign grades for better cost and logistics management

Disadvantages

• Sensitivity to moisture if not properly dried before the process
• Need for precise temperature control in preform injection
• Dependence of final quality on production line settings
