Are you looking for the perfect bottle or jar for your food or beverage product? You may have heard of food-grade safe bottles and cans, but how can you be sure that the glass or plastic cans you choose are food-grade safe? It's time to answer some questions.
The good news is that regulatory agencies around the world have regulations to determine which ingredients are food-grade safe. For the United States, the responsibility lies with the FDA or the Food and Drug Administration.
The FDA regulates everything from dietary supplements to microwave ovens, and they determine the acceptable food-grade packaging options for glass and plastic bottles.
Glass and Food Packaging Bottle, such as bottles, cans, and jugs, are considered by the FDA as indirect food additives-substances that may come into contact with food as part of packaging or processing equipment, but are not intended to be added directly to food.
Let's start with Glass
The FDA has previously recommended that soda lime glass bottles and cans are not "food additives" as defined above. In the field of glass manufacturing, they are divided into Type I and Type III. Both are considered "GRAS", or generally considered safe.
GRAS is the name of the FDA. It is used for chemicals or substances added directly or indirectly to food. Experts believe that it is safe. GRAS was first described in the Food Additives Amendment Act of 1958 and will be updated and retested when new standards become available.

So all in all, glass is generally considered to be food-grade safe.
The complex plastic world
On the other hand, plastic bottles and cans are not that simple. There are many kinds of plastic resin materials: in addition to the well-known PET, HDPE, LDPE, PP, thanks to the wonderful classification of OTHER-7. Some plastic materials or colorant materials are not food-grade safe because they can be recognized as "food additives" by the FDA, but they are not designated by GRAS. Therefore, for plastic bottles, food-grade safety must be specifically tested at the resin and colorant level, not at the finished product level.
For example, clear PET plastic without added colorants is generally considered food-grade safe. Most HDPE resins without added colorants are also considered food-grade safe.
Most plastic bottles and cans sold as food containers and beverage bottles are food-grade safe because the plastic resin used to produce these containers has been independently tested. To confirm that your plastic bottle or jar is food-grade safe, please contact your manufacturer to obtain a resin specification sheet. If your plastic bottle is colored, you must also request a colorant specification sheet. They usually contain information that can answer your questions.
Food packaging is the same, 100ml Plastic Spray Botte is the same. If you want to use 100ml Plastic Spray Bottle more safely, then you have to choose it like a food packaging bottle.
