    Default plastic and glass containers

    Generally, it's best to go through the trouble of buying glass containers when possible.
    This is especially true for tad containers and containers that hold water for our frogs.

    As for the mist bucket---a food safe 5 gallon container should be used as this is a situation where water sits for longer periods of time.

    >What Is Plastic?

    Plastic is made from hydrocarbons derived from petroleum or natural gas. The hydrocarbons are formed into chains called polymers, or plastic resins. By combining hydrocarbon molecules in different ways, different types of plastic can be created.

    What Is Food Grade Plastic?

    The U.S. Food & Drug Administration (FDA) requires that plastics used in food packaging be of greater purity than plastics used for non-food packaging. This is commonly referred to as food grade plastic. Plastics used to package pharmaceuticals are held to an even higher standard than food grade.

    Food grade plastic does not contain dyes or recycled plastic deemed harmful to humans. However, this does not mean that food grade plastic cannot contain recycled plastic. The FDA has detailed regulations concerning recycled plastics in food packaging.

    Another aspect of food grade plastic is matching the appropriate type of plastic to the food in question. Foods that are highly acidic or that contain alcohol or fats can leach plastic additives from the packaging or container into the food. As a result, you should only use plastic containers that are FDA approved for the particular type of food the plastic will come into contact with.

    Finally, it should be noted that a plastic container can no longer be considered food grade if it has been used to store non-food items like chemicals, paint, or detergent.

    Types Of Plastic

    In the United States, the following codes represent the seven categories of plastic used in nearly all plastic containers and product packaging:

    1 - PET PET or PETE (polyethylene terephthalate) is a clear, tough polymer with exceptional gas and moisture barrier properties. PET's ability to contain carbon dioxide (carbonation) makes it ideal for use in soft drink bottles.
    Examples: Soft drink bottles, detergent bottles


    2 - HDPE HDPE (high density polyethylene) is used in milk, juice and water containers in order to take advantage of its excellent protective barrier properties. Its chemical resistance properties also make it well suited for items such as containers for household chemicals and detergents. Most five gallon food buckets are made from HDPE.
    Examples: Milk bottles, shopping bags


    3 - V Vinyl (polyvinyl chloride, or PVC) provides excellent clarity, puncture resistance and cling. As a film, vinyl can breathe just the right amount, making it ideal for packaging fresh meats that require oxygen to ensure a bright red surface while maintaining an acceptable shelf life.
    Examples: Plastic food wrap, shrink wrap, garden hoses, shoe soles


    4 - LDPE LDPE (low density polyethylene) offers clarity and flexibility. It is used to make bottles that require flexibility. To take advantage of its strength and toughness in film form, it is used to produce grocery bags and garbage bags, shrink and stretch film, and coating for milk cartons.
    Examples: Squeeze bottles, dry cleaning bags


    5 - PP PP (polypropylene) has high tensile strength, making it ideal for use in caps and lids that have to hold tightly on to threaded openings. Because of its high melting point, polypropylene can be hot-filled with products designed to cool in bottles, including ketchup and syrup. It is also used for products that need to be incubated, such as yogurt. Many Cambo, Tupperware and Rubbermaid food storage containers are made from PP.
    Examples: Bottle caps, take-out food containers, drinking straws


    6 - PS PS (polystyrene), in its crystalline form, is a colorless plastic that can be clear and hard. It can also be foamed to provide exceptional insulation properties. Foamed or expanded polystyrene (EPS) is used for products such as meat trays, egg cartons and coffee cups. It is also used for packaging and protecting appliances, electronics and other sensitive products.
    Examples: Plastic foam, packing peanuts, coat hangers


    7 - Other Other denotes plastics made from other types of resin or from several resins mixed together. These usually cannot be recycled.
    Another important type of plastic is polycarbonate, a clear shatter-resistant material used in restaurant food storage containers and the Rubbermaid Premier line of stain-resistant home food storage containers.

    Why do we need different types of plastics, anyway? This excerpt from the American Plastics Council website explains it well.

    "Copper, silver and aluminum are all metals, yet each has unique properties. You wouldn't make a car out of silver or a beer can out of copper because the properties of these metals are not chemically or physically able to create the most effective final product. Likewise, while plastics are all related, each resin has attributes that make it best suited to a particular application. Plastics make this possible because as a material family they are so versatile."

    Not All HDPE Containers Are Food Grade

    There is a common misconception that all containers made of white plastic or HDPE plastic bearing the HDPE "2" plastic symbol symbol are food grade containers. This is not true
    >

    Plastics To Avoid

    < Examples include:

    HDPE white plastic containers of unknown food grade status
    Garbage cans or pails
    Mop buckets
    Laundry detergent or kitty litter buckets
    Dry pet food buckets
    5-gallon utility buckets from the home center
    Household storage containers
    Garbage bags
    Any container—even if made of food grade plastic—that has been used to store non-food items like chemicals, paint, or detergent >

    Default Re: plastic and glass containers

    Wow that was very informative. Thanks for all the tips on safe storage for our frogy friends food and water and most importantly the frogs themselves. It is unbelievable how many different containers are harmful for our pets. It is true that glass is safest. I don't like to take chances with plastic myself, so everything that comes in contact with the frogs is glass except their bowl, which are from the pet store. Thanks so much for taking the time to put this together for us!
