For an incomplete pressure box, the most important factor: corrugated cardboard,nailing, cover type, size design.
1, what is the so-called paper? The paper selection of materials, the thickness of the paper, the old and the new, grams etc.
According to the material to points, 3 kinds of paper is the most common: kraft paper (also known as Kraft), tea paperboard, corrugated paper.
Difference.
(1) the most natural color: kraft paper color, corrugated paper yellow gray, tea paperboard, rough.
(2) in soft, hard paper is rich in fiber, toughness, hardness, a considerable degreeis the best, the corrugated paper is kraft paper added by the old material, fiber, few components, the general quality of tea board, corrugated paper carton table, very soft. Determine the most simple way is and he choked paper nail hardness, easy to choke off, worse paper.
(3) weight: because if the material enough reason, kraft paper per square meter is far more than tea paperboard valuable, according to the comparison, 12 post of carton specifications more than 45 grams, kraft paper, tea paperboard is not more than 35 grams.
(4): materials selection and, tea paperboard prices the most advantage of the price.
B, according to the paper focus (mainly in the eastern city method), K paper,weighs 200 grams; a paper, weight is 160 Ğ; B paper, weighs 120 grams, W paper(white), weight 125 grams.
Error: there is a large part of A3B box, B3C seller, B5B, = C and other statements,many property buyers think, A3B is the best in quality, B3B is weak. In fact, theletters, such as A, said one paper per square metre weight is 160 grams, theparticular specifications a paper carton, carton is heavy, exactly how quality,property buyers can "see. Not rule out according to A3B this representation is a unique professional, but today, there are many buyers and sellers use cartonknowledge scotoma, A3B, or more precisely, the blind trust this box has been formed, high-quality crazy carton, confuse buyers audio-visual.
2, the classification of corrugated board:
Even if the use of the same quality of the face, in the paper and the paper because of the difference of Leng form, properties of corrugated board also has certain difference. International Corrugated Leng form is divided into four, respectively. A stare face expressionless, C type, B type and E type Leng leng. Their requirementsare shown in the following table:
Difference.
Type a stare blankly made of corrugated cardboard, with buffer was good, the richdegree of elasticity;
C A Leng Leng second, but it is the type and degree of impact resistance is better than one.
B type corrugated packing density, surface made of corrugated board, high voltage tester, suitable for printing
E type corrugated due to the thin and dense, the more power
Misunderstanding two: many sellers said he is tile cartons, according to people'sthinking habit, the ceramic tile that intuition is that compared to B, C E. is better,there is no quality comparable to each of the corrugated, advantages and disadvantages of each their own, such as postal box, the overall standard of smaller, limited space of carton the tiles, overly strengthen carton, buffer, andpayment of the price, the more narrow the own ability is limited, and B, C two is more suitable for post office box performance of corrugated.
3, cover type, nail method
Layer: common carton is divided into three layers, five layers, are generally notafraid of merchandise selection pressure of three layers (but must ensure thatthree cartons of good quality, watERProof seal), afraid of pressure impact and electronic products precious fear and the five layer is the general carton.
Cover type: consists of full cover type, semi batch and the heaven and the earthand cover, P.O. Box 1-10 all use of cover types, selling, almost half of cover types,gift box cover most of the heaven and the earth, the bracelet. Wait
Nail method: the most common is divided into two kinds of adhesive and nails, nailusually set three pieces, in the paper is not easy to break, nail sleeve, is a kind ofvery strong bonding method. The concept and aesthetic value of the most popular,adhesive, adhesive looks growth level off is smooth, very beautiful, but the choiceof glue must take good close, otherwise they will be a period of time frame, the sealing place will be broken.
