Sauces are ready-to-eat food, and the quality of sauces can be affected by light. Therefore, to reduce the effect of ultraviolet light on product quality, the packaging material needs to be able to "hide the light source".

From the material point of view, plastic film is very suitable for sauce product packaging. Common materials include polyester/vinaigrette special polyethylene, nylon/polyethylene, polyester/aluminized/polyethylene, etc. The first is a common common material, can be made into transparent film, can also be printed with patterns, text and other information. The second because it is nylon material, so more soft, toughness, not easy to break the bag, fried bag, is also a transparent film, can print patterns. The third is aluminized material, there is a layer of aluminized film in the middle, which can avoid light, moisture-proof and improve the grade of products. Its feel is relatively hard, and it is not easy to break the bag. Some sauces use aluminum plastic compound packaging more, such as some hoisin sauce, meat sauce and so on. These packages are beautifully printed to extend shelf life. This kind of bag packaging, generally need to set easy to tear mouth, convenient for consumers to use. This form of packaging is more suitable as a sauce for a companion product. Cost-effective, the price is relatively low.

In addition, the sauce used in life, can choose glass bottle packaging, convenient to open and close many times. Some sauces also have an aluminum-plastic sealing film to extend shelf life. A jar is a common form of jar, especially for jam. But there are some sauces that use narrow mouth bottles, such as chili sauce and ketchup. Special-shaped bottles mainly appear on some dressing packages, such as salad dressings. Bottles used as sauce packages may need to be added with ingredients to block UV rays, either by labeling the bottles or by wrapping them in plastic.
