Crop (anatomy) Crop (anatomy) A crop (sometimes also called a croup or a craw, or ingluvies) is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion. This anatomical structure is found in a wide variety of animals. It has been found in birds, and in invertebrate animals including gastropods (snails and slugs), earthworms, leeches, and insects. Cropping is used by bees to temporarily store nectar of flowers. When bees "suck" nectar, it is stored in their crops. In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat.
Pouch laminator Pouch laminators are designed for moderate use in the office or home. For continuous, large-volume lamination projects, a roll laminator performs more efficiently. Pouches can be bought with different thicknesses in micrometres. Standard home or office machines normally use 80–250 micrometre pouches, depending on the quality of the machine. The thicker the pouch, the higher the cost. Pouches can also measured in mil, which equals one thousandth of an inch. The most common pouch thicknesses are 3, 5, 7 and 10 mil (76,127,178 and 254 μm). Certain pouches such as butterfly pouches can be used with a pouch laminator to
