company news about Why can the surface of bamboo products be smooth？

You won't be surprised to hear that bamboo food containers are made of bamboo, but they are treated to ensure they are durable and hygienic.

A common way to treat bamboo used in food containers or plates is to apply a food safe coating or finish. This coating can help protect the bamboo from being stained and can also make it easier to clean. Coatings can be made from a variety of materials, such as natural oils, waxes, or paints.

There are several food-safe oils, waxes, and lacquers that are commonly used to finish bamboo products, including:

Mineral Oil: Mineral oil is a food-safe, non-drying oil that is often used to protect and seal bamboo. It is easy to apply and helps to prevent staining and moisture damage.

Beeswax: Beeswax is a natural wax that can be melted and applied to bamboo to create a protective coating. It is non-toxic and safe for use with food, but it may need to be reapplied periodically to maintain its effectiveness.

Carnauba Wax: Carnauba wax is a plant-based wax that is often used in combination with other waxes to create a durable and water-resistant coating. It is also food-safe and non-toxic.

Shellac: Shellac is a natural resin that can be dissolved in alcohol to create a varnish-like coating. It is safe for use with food and can create a glossy, protective finish.

Polyurethane: Polyurethane is a synthetic coating that is sometimes used on bamboo products to create a durable, water-resistant finish. Food-grade polyurethane is safe for use with food and can provide a long-lasting protective layer.
