These wraps are made of 4mm black polypropylene (corrugated plastic) with 5% UV protection. They are lightweight, designed to fold and store flat, and have been tested to have little water absorption. Folds have a living hinge of 21,000 cycles. They have one heat welded seam. They have four, 10” flaps on the top.

You will need to make a 3/4” to 1” wide, top entrance hole with a punch, hole saw, or blade knife to exhaust moisture created by the bees. Put this hole at the center front of the hive, just below the upper lid. There is room in the front of the hive for bees to crawl around before leaving the wrap.

The wraps have room for about 1.5” of insulation above the inside lid of the hive. Put a large stone or brick over the top lid. It's best to leave the wraps on the hives until late April/early May They can be temporarily taken off earlier in the spring to do colony inspections, but slide right back on, with no issues.

These wraps are for 10-frame Langstroth hive bodies. These wraps are recyclable.
