A biodegradable liquid container carrier is made from molded pulp or fiber and is designed to grasp liquid containers at the top portion thereof. As a result, less material is used in the manufacture of the carrier. This is made possible by a combination of a wet end treatment with a fatty acid modified PET during processing of the pulp mass before forming the pulp mass into a liquid container carrier. A base coat that is 10-80% clay or pigment, 20-90% styrene-butadiene latex and 0-15% fatty acid modified PET and a top coat that is 75-100% fatty acid modified PET and 0-25% clay mixture onto the base coat are then applied to the molded liquid container carrier. These treatments greatly enhance the strength, rigidity and water-resistance of the carrier. However, the carrier is still biodegradable and will biodegrade in 90 days under composting conditions. |
