Which type of tape is used primarily to hold floral foam in place and is waterproof?

Anchor tape is specifically designed for securing floral foam in place within arrangements. Its waterproof nature allows it to adhere effectively to surfaces without being affected by moisture, making it ideal for use with wet foam. This ensures that the foam remains stable and does not shift within the container, which is crucial for maintaining the structure and aesthetic of the floral arrangement.

Floral tape, while useful for other purposes such as binding stems together, does not provide the same level of adherence and is not waterproof, which makes it less suitable for securing foam. Waterproof tape may imply a general adhesive quality, but it does not have the specific design or properties tailored for floral applications. Sticking tape, often used in various crafting contexts, similarly lacks the specialized features required for floral foam stability.
