One, the choice of the material that pack

The earliest container most is to use plant material to be made, if use leaf, bulrush and culm to the course is braided and be become, design facilitate the form that lets people carry. After, people uses domestic animals to carry, the dimension of packing also increases subsequently, the use data that pack also tends diversification.

Current, the outer packing data that our country fruit uses is very much, basically can divide for the following 5 sort:

Basket: The basket that makes up with the natural plant material such as bamboo, twigs of the chaste tree is the traditional container of our country. The main good point of this kind of material is petty gain, light, use local materials, can make up the container of aleatoric appearance and size almost. Defect is appearance irregular, often very not solid. Be not worth what injure in order to prevent to happen consequently; Size is larger, with easy exhaustion of person tool drive; Appearance is to go up big normally small, although can reduce pressure of susceptive of lower level fructification, but there is yard of the caboodle that make the land hard in carry and storing up.

Wooden case: The container that wooden case makes than material of other and natural plant is close friends, ordering an advantage is strong, can make the appearance that unites into all sorts of norms, the ability that than other data preventive manage injures is ambitious. But, wooden case itself is heavier, operate and carry more demanding.

Carton: Corrugated fibreboard box is the child of western technology, it is light, cheap, serve as wooden case consequently replace content, a large number of in water occurrence

Fruit is current domain. The surface that another advantage of carton is it is slicker facilitate use black-and-white label and propaganda paterial, the drawback with the biggest carton is to cannot repeat use, once leach corrode or treatment extensive are easy,be injured.

Plastic box: Plastic box can use a variety of synthesis material to be made, but basically be by the following two kinds of material make: Harder high density polyethylene, softer low density polystyrene. High density spends polyethylene box, strong, intensity is high, endure very easily case current in in all sorts of pressure that can encounter usually, and can pile a certain height; In the meantime, because this kind of case makes uniform standards easily, consequently the can biggest use store up space; Strength is great, there is bigger flexibility on the design, still can increase shake handshandle and airway to wait on box wall, and won't weaken Ding child mechanical intensity. In addition, clean easily, outside and smooth, can make a variety of bright color. If make the case can be covered each other when the design,rise, place of so empty case occupies a space to have full case only 1/3 the left and right sides or fewer.

People thinks these model material or blank bin are satisfying fresh fruit vegetable current requirement side has better technical character, be regarded as in project of the any development that pack so of traditional container replace content. But, polyethylene data is very valuable, use case that reclaim in effectively organization only and makes below, using this kind of case just is feasible economically.
