Food plastic bottles are one of the common food packaging containers in our daily life. In order to ensure the quality and safety of food, various countries have corresponding standards and specifications. In China, the national standard for food plastic bottles is GB/T 21256-2007 "Food Plastic Bottles". The international standard for food plastic bottles is the responsibility of the International Organization for Standardization (ISO), which includes ISO 22000:2018 "Food Safety Management Systems - Requirements" and ISO 18602:2013 "Plastic Products for Food Applications".

F-700C

GB/T 21256-2007 "Plastic Food Bottles" is a Chinese national standard that specifies the requirements for the classification, materials, structure, mechanical properties, physical properties, transparency, external dimensions, printing, and labeling of food plastic bottles. The following will provide a detailed introduction to the main content of GB/T 21256-2007 "Plastic Bottles for Food" standard.

1、 Classification and material requirements

The GB/T 21256-2007 standard divides food plastic bottles into several categories, including mineral water bottles, carbonated beverage bottles, fruit juice bottles, edible oil bottles, soy sauce bottles, etc., and proposes corresponding material requirements for different types of bottles. For example, mineral water bottles should be made of high transparency polyester material, carbonated beverage bottles should be made of polyester material with high pressure resistance, and juice bottles should be made of polyester material with good acid and alkali resistance.

2、 Structural and mechanical performance requirements

The standard stipulates that food plastic bottles should have certain structural and mechanical properties to ensure their stability and function during normal use. For example, the bottle mouth structure should be designed reasonably to ensure sealing and convenient use; The bottle wall should have sufficient thickness and strength to withstand pressure and external forces; There are also corresponding requirements for compressive performance and verticality.

3、 Physical performance requirements

The physical properties of food plastic bottles are also one of the concerns of the standard. The standard specifies the physical performance requirements for food plastic bottles, including transparency, heat resistance, cold resistance, boiling water deformation, and resistance to ketone food solutions. For example, transparency should meet certain requirements to ensure that consumers can clearly see the food inside the bottle; Heat resistance requirements can ensure that the bottle does not lose its shape and strength in high-temperature environments; The requirement for cold resistance can ensure that the bottle does not become brittle or break at low temperatures.

4、 External dimensions, printing and labeling requirements

The standard also has corresponding requirements for the external dimensions, printing, and labeling of food plastic bottles. The external dimensions of the bottle should meet the design and manufacturing requirements, and have corresponding tolerances; Printing and labeling should be clear, not easily detached, and labeled in accordance with relevant laws and regulations.

In summary, GB/T 21256-2007 "Plastic Food Bottles" is a Chinese national standard that specifies the requirements for the classification, materials, structure, mechanical properties, physical properties, external dimensions, printing, and labeling of food plastic bottles. The formulation and implementation of these standards can ensure the quality and safety of food plastic bottles during production and use, and protect the rights and interests of consumers. Therefore, when selecting and using food plastic bottles, attention should be paid to whether they meet the relevant standard requirements to ensure our health and safety.
