The casket is a large shipping container, often made of wood, usually used for transporting or storing large heavy items. Steel and aluminum crates are also used. Chests specifically designed for specific products, and often made reusable, such as "bottle crates" for milk and soft drinks.
Crates can be made of wood, plastic, metal or other materials. The term crates often implies a large and powerful container. Most plastic crates are smaller and more commonly called boxes or containers. Metal is rarely used because of its weight. When the metal is used, the crate is often made as an open casket and can be called a cage. Although chests may be made of any material, for this reason, the term 'wooden crates' used alone often implies a single made of wood.

Wooden crates have a stand-alone structure, with or without a sheath. For wooden containers to be crates, six sides must be installed to produce container-identifiable power. Crate is different from wooden box. The strength of the wooden box is judged on the weight that can be brought before the top (top, end, and side) is installed, while the strength of the crate is ranked top in place. In general conversation, the term coffin is sometimes used to indicate a wooden box.
History
The first documented reference to the shipping crates in the United States is in the 1930 handbook, Technical Bulletin No. 171 written by C. A. Plaskett for the U.S. Department of Agriculture His writing implies that the chest was defined before that time. Plaskett is known for extensive testing and defining the various components of transport packaging. The USDA Forestry Service revised and expanded it in 1964 as "Wooden Craft Design Guidelines", Handbook 252.
Construction
Although the definition of wooden crates, compared to wooden boxes, is obvious, the construction of both often produces an unclear container of crates or boxes. Both wooden crates and wooden boxes are built to load unique items, either designs of crates or boxes can use the principles of both. In this case, the container will usually be determined by how the angle and angle of the container is built. If the coating (either plywood or wood) can be removed, and the framed structure will remain standing, the container will likely be called a crate. If removal does not result in binding of wood around the edge of the container, it may be called a wooden box.
Design
There are many variations of wooden crates design. By far the most common are 'closed', 'open' and 'framed'. Closed Crates are fully or almost completely covered with materials such as plywood or wooden planks. When wood is used, cracks are often left between boards to allow for expansion. Open crates are one that (usually) uses wood for coating. This sheath is usually tied up by various distances. There is no strict definition of open crates compared to closed crates. Usually when the gap between boards is greater than the distance required for expansion, the crate will be considered an open casket. The gap between the boards is usually not greater than the width of the sheath board. When the gap is larger, the board is often considered 'cleat' rather than sheathing so that the rendering of the casket is unsheathed. The veil is a frame box. Frame Crate is only containing the frame structure and no material is added for surface protection or protection. Usually open crates will be constructed of 12 pieces of wood, each along the outer edge of the content and more wood is placed diagonally to avoid distortion of the torque.
When all types of crate reach a certain size, more boards can be added. This board is often called Cleat. A cleat is used to provide support to the panel when the panel has reached a size that may require additional support based on the transport method. Cleats can be placed anywhere between the edge of the given panel. In crate, cleat placement is often determined by the width of plywood used in wooden plywood sheets. In other chests, cleats are often given the same distance to strengthen the panel. Sometimes two cleats are added over the top panel of the crate which is placed as necessary to provide the top of the added chests of strength in which the lifter or rope chains can be pressed on the crate when lifted.
Cleats may have more specific names based on the added benefits they provide. Some published standards use only more descriptive terms and may never refer to these timber components as cleats. For example, the wood placed under the top of the wooden container to add support for the large top is called the "wooden block". The wood is built in the center of the top of the wooden container to strengthen the top called "cleat". When cleats are enlarged and built to support large upper parts, they can generally be called "cleats" or more specifically called "joists".
"Skids" or thick bottom runners, sometimes determined to allow forklift truck access to lift.
Methods of transport and storage conditions should always be considered when designing crate. Each step of the transport chain will produce different pressures of shock and vibration. Differences in pressure, temperature, and humidity may not only affect the contents of the crate, but will also affect the strength of the fasteners (mostly nails and staples) in the crate. In some countries, every wooden casket designed to be shipped abroad should be treated with ISPM 15 standards or commonly known as "bug caps" to prevent the spread of disease and insects.
Although the above definition is almost always true, there are many minor changes or 'sub-definitions' used by and across organizations, institutions and documents. This is the result of a small size industry and the fact that a limited definition of a different item each time is made can be difficult to define.
IATA, the International Air Transport Association, for example, does not allow crate on aircraft because it defines a crate as an open transportation container. Although the crate can be of Open or Framed varieties, it does not have a sheath, the sealed chest is not open and is just as safe to ship as a wooden box, which is permitted by IATA.

Other chests
Milk crates and bottle crates are a reusable form of packaging that is used to ship to retail stores and return empty bottles to bottles or packers. This is usually a molded plastic design expected to make some round-trip deliveries. Wooden structures are also used.
