Plastic seasoning bottles are a common packaging form in our daily life, which can effectively protect the freshness of seasonings and have functions such as leak prevention and corrosion prevention. However, choosing the right plastic bottle for seasoning is also a discipline. This article will provide you with a detailed introduction to the precautions for selecting plastic bottles for seasoning, hoping to help you make the right purchasing decision.

 Material selection

When choosing plastic bottles for seasoning, the first thing to pay attention to is their material. Common plastic bottle materials include PET, PP, PE, etc. Here is an introduction and comparison of these materials:

1. PET material

PET material is a common food grade plastic bottle material, which has excellent transparency and temperature resistance, can withstand high temperatures, and is not easily deformed. In addition, PET plastic bottles have good airtightness, which can effectively prevent external air from entering and protect the freshness of seasonings. Therefore, if the seasoning you purchase is susceptible to oxidation, PET plastic bottles are a good choice.

2. PP material

PP material is a plastic material with good weather resistance and high temperature resistance, which can withstand high temperatures and is not easily deformed. In addition, plastic bottles made of PP material are not easily moldy and have a certain degree of corrosion resistance. Therefore, if the seasoning you purchase has a certain spicy or sour taste, you can consider choosing PP plastic bottles.

3. PE material

PE material is a plastic bottle material with good flexibility, impact resistance, and heat resistance. PE plastic bottles are commonly used for packaging liquid condiments, such as soy sauce, vinegar, etc. It has good sealing and leak proof performance, which can effectively protect the quality and taste of liquid seasoning.

In summary, when choosing the material of plastic bottles for seasoning, it is necessary to decide based on the nature and requirements of the seasoning. Generally speaking, PET material is suitable for seasonings that are prone to oxidation, PP material is suitable for seasonings with spicy or sour taste, and PE material is suitable for packaging liquid seasonings.

 Sealing performance

The sealing performance of plastic seasoning bottles is one of the important indicators to measure their quality. Good sealing performance can effectively prevent the oxidation, drying, and invasion of odors in seasonings, maintaining their freshness and taste.

1. Observe the quality of the bottle cap and mouth

The quality of the bottle cap and mouth directly affects the sealing performance of the seasoning plastic bottle. Firstly, check whether the bottle cap is intact and undamaged, and whether there is any deformation or damage; Secondly, it is necessary to check the fit between the bottle cap and the bottle mouth to ensure complete sealing; Finally, try tightening the bottle cap and check its flexibility in rotation.

2. Pay attention to the appearance of the bottle body

Sometimes, plastic seasoning bottles may have obvious appearance defects on the bottle body, such as bubbles, dents, etc. These defects are likely to cause leakage in the bottle body. Therefore, when making a purchase, it is important to carefully observe the appearance of the bottle body to ensure that its surface is smooth and defect free.

3. Conduct a simple sealing test

When selecting plastic bottles for seasoning, a simple sealing test can be conducted to determine their sealing performance. The specific method is to seal the bottle mouth with the palm of your hand, squeeze the bottle body with force, and observe whether there are any bubbles overflowing. If bubbles overflow, it indicates poor sealing performance and is not recommended to purchase.

Safety performance

The safety performance of plastic seasoning bottles is another important factor that must be considered when purchasing. Here are some things to pay attention to:

1. Confirm if it is food grade plastic

When purchasing plastic bottles for condiments, priority should be given to food grade plastic bottles to ensure their safety for human health. Food grade plastic bottles usually have relevant labeling and certification on food packaging, and consumers can carefully check the labeling and instructions on product packaging.

2. Pay attention to avoiding hot drinks and food

Plastic bottles can release harmful substances such as BPA in plastics when heated. Therefore, when choosing plastic bottles for condiments, it is advisable to avoid using them for hot drinks and food to reduce the intake of harmful substances.

3. Pay attention to preventing direct sunlight

Seasoning plastic bottles should avoid prolonged exposure to sunlight, as the ultraviolet rays in sunlight can cause the bottles to deteriorate and release harmful substances. Therefore, when storing seasoning plastic bottles, it is important to choose a cool and dry environment.

Size capacity

When choosing plastic bottles for condiments, capacity selection is also a factor to consider. Here are some suggestions:

1. Select based on frequency of use

If you frequently use a certain seasoning, you can choose larger plastic bottles to reduce the frequency of frequent purchases. For example, large capacity soy sauce bottles, edible oil bottles, etc.

2. Do not purchase in excess

Sometimes, due to sufficient supply or favorable prices, we may purchase seasonings in excess. However, excessive purchases may lead to the seasoning being stored for too long, making it prone to spoilage. Therefore, when choosing plastic bottles for seasoning, it is important to choose the appropriate capacity according to personal needs and avoid excessive purchases.

5、 Organic certification

In recent years, more and more consumers have begun to pay attention to the safety and health of food, and organic products have become the first choice for many people.
