Introduction to common materials of Plastic Spice Jars cans

1. Polyethylene (PE):

Polyethylene is a common plastic material widely used in the food packaging industry. It has good toughness and impact resistance, which can effectively protect the freshness of food. PE has strong acid and alkaline resistance and is not easily corroded by chemicals, making it an ideal material for seasoning cans.

2. Polypropylene (PP):

Polypropylene is also a common food grade plastic material with high thermal stability and heat resistance. It can withstand foods at higher temperatures and is suitable for seasoning cans that require heating. In addition, polypropylene has excellent chemical corrosion resistance and toughness, which can ensure the safety and durability of the seasoning tank.

3. Polystyrene (PS):

Polystyrene is a commonly used plastic material, commonly used in packaging cups, food containers, etc. However, for seasoning cans, it is not the best choice. Due to its relatively loose structure, polystyrene is prone to adsorbing fats and flavors from food, and is not resistant to high temperatures and is prone to deformation. Therefore, it is not suitable for long-term storage of seasonings that require heating or high fat content.

4. Polyvinyl chloride (PVC):

Polyvinyl chloride is a commonly used material for packaging and manufacturing plastic products, but it is not suitable for storing food. PVC contains some harmful substances to the human body, such as heavy metals and plasticizers, which can have a certain impact on human health after long-term use. Therefore, it is not recommended to store seasoning in PVC products.

5. Polyethylene terephthalate (PET):

PET is a plastic material with high transparency and strong impact resistance, commonly used in the production of food packaging bottles and beverage bottles. It has good acid alkali resistance and permeability resistance, and has a good preservation effect on food. However, PET has poor temperature resistance and is not suitable for storing high-temperature food or seasoning that requires long-term heating.

6. Polycarbonate (PC):

Polycarbonate is a high-strength and transparent plastic material commonly used in the food packaging industry. It has excellent high-temperature resistance and impact resistance, suitable for some seasoning tanks that require heating. However, for long-term storage of acidic or alkaline foods, PC is not suitable for use due to its high solubility.

Considerations for selecting the best plastic material

1. Food safety:

When choosing Plastic Spice Jars cans, food safety is a crucial factor. Qualified materials should meet food grade standards, contain no harmful ingredients to the human body, and have undergone relevant certification and testing. This ensures that the food stored inside will not be contaminated.

2. Temperature resistance:

Different food seasonings have different storage and usage requirements, so the temperature resistance of Plastic Spice Jars cans also needs to be considered. Some seasonings need to be stored or heated at high temperatures, so it is necessary to choose high-temperature resistant materials. For some seasonings that require long-term storage, materials with poor temperature resistance may lead to food spoilage.

3. Corrosion resistance:

Some seasonings are acidic or alkaline, so it is necessary to choose plastic materials that are resistant to acid and alkali. Only in this way can we ensure that the seasoning does not corrode the tank body and maintain its integrity and stability.

4. Air tightness:

The airtightness of Plastic Spice Jars cans is crucial for maintaining the freshness of the seasoning. Suitable materials should have good airtightness, effectively blocking the entry of air and moisture, and avoiding seasoning from becoming damp or deteriorating.

5. Durability:

Choosing durable plastic materials can extend the service life of seasoning cans. Some materials have strong resistance to impact and wear, which can ensure that the seasoning tank maintains its appearance intact during long-term use.

 Summary and suggestions

In summary, the optimal material for selecting Plastic Spice Jars cans should comprehensively consider factors such as food safety, temperature resistance, corrosion resistance, airtightness, and durability. Polyethylene (PE) is a suitable choice for storing most common seasonings due to its excellent acid alkali resistance and impact resistance. Polypropylene (PP) has high thermal stability and chemical corrosion resistance, making it suitable for seasonings that require heating and long-term storage. However, for seasonings that require heating or storage of acidic and alkaline foods, it is recommended to choose materials with higher temperature resistance, such as polycarbonate (PC). In the actual selection process, attention should also be paid to whether the purchased seasoning can meets the requirements of food grade. Before purchasing, the relevant certification and testing reports of the product can be carefully reviewed to ensure food safety.

In daily life, we may be accustomed to using Plastic Spice Jars cans to store various seasonings, but it is important to note that the storage time should not be too long. It is also necessary to replace the seasoning cans in a timely manner and keep the inside dry and clean. In addition, it is recommended to add seasoning
