What is the scope of use of seasoning plastic bottles

Seasoning plastic bottles are a widely used packaging form, and with the improvement of people's living standards, the application of various seasonings on family dining tables is becoming increasingly common. Plastic seasoning bottles determine the freshness and safety of food, and are crucial for people's health. Therefore, it is necessary for consumers to understand the scope, characteristics, and quality standards ofSeasoning plastic bottles. This article will provide a detailed introduction to the scope of use of plastic bottles for condiments.

 Types of plastic bottles for seasoning

1. Plastic bottle

Plastic bottles are a very popular form of seasoning packaging. It is mainly made of materials such as polyethylene (PE) and polypropylene (PP), which are non-toxic, odorless, acid resistant, alkali resistant, heat resistant, pressure resistant, and have good sealing performance, ensuring that the seasoning is not polluted or affected by the external environment inside the bottle. Plastic bottles have the characteristics of smooth surface, transparency, impact resistance, and strong flexibility, making it convenient for consumers to observe the usage of seasoning and easy to use and store.

2. Glass bottle

Glass bottles, due to their hard texture, high temperature resistance, corrosion resistance, and clear transparency, are more suitable for high-end seasonings that have been stored for a long time, such as pickled products such as wine vinegar and turnips.

 Scope of use of plastic bottles for condiments

1. Edible oil

Edible oil is one of the main applications of plastic bottles for condiments. According to transportation and storage needs, common oil bottles have capacities ranging from 250 milliliters to 2 liters, and plastic materials can effectively isolate air and sunlight. In addition, the sealing and pressure resistance requirements of the oil bottle are high to avoid leakage and damage during filling.

2. Soy sauce

Soy sauce bottles are another common plastic seasoning bottle. Soy sauce is in a liquid state, and plastic bottles have good sealing performance, which can protect the amino acids and nitrogen nutrients in soy sauce and extend its shelf life. Due to its compact and lightweight nature, soy sauce bottles are easy to carry and are more suitable for use in the catering industry and households.

3. Seasoning vinegar

Seasoned vinegar is also often filled in plastic bottles. Vinegar has a unique flavor and taste, and its healthy characteristics make it an indispensable part of modern family health life. Due to the high acidity and irritation of seasoned vinegar, the sealing performance of plastic bottles is particularly important to prevent oxidation reactions such as vinegar and external air.

4. Seasoning sauce

Seasoning sauce bottles often use plastic materials, such as bean paste, chili sauce, etc. These sauces have a small volume and often require high sealing performance of plastic bottles, which can effectively prevent oxidation and decay, making product quality more stable.

5. Meat seasoning

Hot pot base, ham bag with essence, seafood seasoning and other meat seasonings are also suitable for packaging plastic bottles. This type of meat seasoning requires plastic bottles to have good durability and be able to withstand certain temperatures and acids and alkalis due to the residual substances such as fat. Therefore, the selection of plastic bottles should take into account product characteristics and meet the needs of filling and storage.

 Quality standards for plastic bottles for condiments

Plastic seasoning bottles should not only meet the usage characteristics of the product, but also meet the safety and hygiene requirements for food storage. On the basis of meeting the above basic requirements, plastic seasoning bottles can establish higher quality standards according to the usage needs of different seasonings.

1. Safety standards

Plastic seasoning bottles need to consider their safety when selecting materials. The relevant provisions of the "Intermediate Quality Standards for Food Contact Materials" issued by the Ministry of Health should be selected. These materials can ensure that plastic bottles do not produce harmful substances, as well as odors, toxins, and harmful substances, to protect food quality and consumer health.

2. Physical standards

Seasoning plastic bottlesshould have good pressure resistance and sealing performance according to physical standards. The material strength should be greater than the product pressure, otherwise it may cause deformation of the plastic bottle and water evaporation of the stored product. At the cork of the bottle cap, it should have excellent sealing performance to ensure that the food moisture and nutrients inside the packaging will not be lost or evaporated.

3. Chemical standards

Seasoning plastic bottles should have good chemical stability, and have characteristics such as acid resistance, alkali resistance, high temperature resistance, and low temperature resistance. These characteristics are designed for different seasonings, such as soy sauce that can be filled at high temperatures, while seasoning vinegar needs to be set at room temperature. Therefore, the chemical standards required for plastic bottles vary for different seasonings.

4. Aesthetic standards

The shape, color, and pattern of plastic seasoning bottles are also important factors to consider when choosing. Generally speaking, choosing plastic bottles with good transparency, bright color, and beautiful appearance can better highlight the product's identification ability, improve consumers' purchasing desire and satisfaction.
