A box (plural: boxes) is a container used for the storage or transportation of its contents. Most boxes have flat, parallel, rectangular sides. Boxes can be very small (like a matchbox) or very large (like a shipping box for furniture ), and can be used for a variety of purposes from functional to decorative. Boxes may be made of a variety of materials, both durable, such as wood and metal; and non-durable, such as corrugated fiberboard and paperboard. Corrugated metal boxes are commonly used as shipping containers. Most commonly, boxes have flat, parallel, rectangular sides, making them rectangular prisms; but boxes may also have other shapes. Boxes may be closed and shut with flaps, doors, or a separate lid. They can be secured shut with adhesives, tapes, or more decorative or elaborately functional mechanisms, such as a catch, clasp or lock.
Clear plastic boxes are made of PVC/PET/PP/PS and other related plastic products, such as transparent folding boxes, cylinders, sky and earth cover boxes, hand bags, hanging cards and other related plastic products, UV offset printing, silk screen printing, bronzing/silver, frosted and other printing effects can be achieved. Plastic is a synthetic or natural polymer resin as the main material. After adding various additives, it has ductility under a certain temperature and pressure, and can fix its shape after cooling. The process in which natural or synthetic polymer resin molecules are in a molten state and the auxiliary molecules are evenly distributed around it is called plasticization. This process has been reached, and it has not been reached. It is considered to have not been plasticized. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, plastic 25%, metal 25%, and glass 15%. Plastic packaging boxes have the following advantages: 1. Easy to form, as long as the mold is replaced, different varieties of containers can be obtained, and it is easy to form mass production; 2. The packaging effect is good, there are many kinds of plastics, easy to color, and the color is bright, and various kinds of packaging containers can be made according to the needs to achieve the best packaging effect; 3. It has good corrosion resistance, acid and alkali resistance, oil resistance and impact resistance; and has good mechanical strength.
A decorative box is a form of packaging that is generally more than just functional, but also intended to be decorative and artistic. Many such boxes are used for promotional packaging, both commercially and privately. Historical objects are usually called caskets if larger than a few inches in more than one dimension, with only smaller ones called boxes. Traditionally gift boxes used for promotional and seasonal gifts are made from sturdy paperboard or corrugated fiberboard. These boxes normally consist of a base and detachable lid and are made by using a die cutting process to cut the board. The box is then covered with decorative paper. Gift boxes can be dressed with other gift packaging material, such as decorative ribbons and gift tissue paper.
