Plastic bottles are widely used in beverages, condiments, snack storage tanks, etc., and medicinal plastic bottles are also commonly used. Among them, the choice of packaging materials for food plastic bottles is the key to ensuring the stability of raw materials. Do you have such doubts? Some food plastic bottles are brown. Why? The following editor will give you some popular science.

Colored food plastic bottles are added with sedan in the raw materials for the protection of food seasoning. There are many types of seasonings, some of which will react in the light and reduce the original flavor of the seasoning, so these light-sensitive seasonings need to be stored in brown containers. Since some spices are sensitive to light, why not use a black bottle? This is because melanin means that the incoming light is completely absorbed and there is no reflected light. If the bottle is black, it will be opaque. One of the purposes of using the brown bottle is that the user can observe the amount of ingredients in the bottle before and after use, so that they can take it prepared.

The brown bottle can not only filter most of the visible light, but also ensure the transparency of the bottle for easy observation. Therefore, brown plastic bottles are often used as light-sensitive food plastic bottles.

In the process of manufacturing plastic bottles and caps from plastic pellets, the following issues need to be addressed:

(1) Drying of plastic particles: Before making bottles, plastic particles should be stored in hot air drying materials to avoid moisture absorption of plastic particles. Bottles made of hygroscopic plastic have lines that affect the clarity and appearance of the bottle.

(2) Feeding and dust removal of plastic bottles: Plastic particles generally use a vacuum feeding system. Because the particles are a mixture of fresh and recycled materials, there will be some fine particles, and the feeding system needs to consider dust removal measures.

(3) Recycling of plastic particles: the currently used bottle making machines and cap making machines have leftovers, which need to be crushed and added to the mixer (mixed with fresh materials) for recycling. Since different materials may be used for the bottle body, inner and outer caps and rings, the recycling system should be divided into sub-systems based on the materials used.
