Yes. Bioleader® supports OEM logo printing and private-label designs for 1000ml rectangular paper salad bowls and matching paper lids — ​ high quality microwave safe to-go containers.

Yes. Bioleader® 500-650ml square paper salad bowls with lids are suitable for salads, rice bowls, cold meals, light takeaway meals, and prepared food programs. The food-grade paperboard structure, coated surface, rolled rim, and matching PP or PET lid options help improve stacking, handling, and transport performance , ​ high quality microwave safe to-go containers.

Paper lids are recommended when the buyer wants a consistent kraft or white paper packaging appearance. PP lids are practical for hot food handling, microwaveable use, stacking, takeaway, and delivery. PET lids are suitable when product visibility is important for chilled salads, sushi-style meals, supermarket display, and grab-and-go food programs.

Polypropylene is a semi-crystalline polyolefin thermoplastic — ​ high quality microwave safe to-go containers. Its molecular structure gives it a useful balance of low density, chemical resistance, moisture resistance, toughness and higher heat stability than many common cold-food plastics. PP can be injection-molded or thermoformed into thin-wall bowls, rectangular meal boxes, divided trays and matching lids. The resin grade, crystallinity, wall thickness, reinforcing ribs and molding conditions influence the finished product.

Microwave ovens transfer energy primarily to water and other polar components in food. The resulting heat then moves into the container wall, coating, seal and lid. This is why the same package can behave differently with broth, rice, oily curry, sugary sauce or a frozen prepared meal. Container geometry also matters.
