纸护角选择应该注意哪些事项?

来源:http://www.shuangfengbaozhuang.cn 时间:2021-01-12

纸护角的纸板选择是获取顾客订单的第一步,也是关键的一步,只有准确合理的选择好纸护角,顾客的成本接受能力,才能赢得订单,使顾客满意,确保在激烈的市场竞争中建立稳定的客户关系,并保持一定的利润空间,使企业得以持续发展。
The paperboard selection of paper corner guards is the first and key step to obtain customers' orders. Only by choosing paper corner guards accurately and reasonably and meeting customers' cost acceptance ability, can we win orders, make customers satisfied, ensure the establishment of stable customer relationship in the fierce market competition, and maintain a certain profit margin, so that the enterprise can continue to develop.
1、纸护角的种类选择
1. Selection of paper corner protectors
纸护角的种类一般分为单面纸护角、三层纸护角、五层纸护角和七层纸护角,单面纸护角是由一张面纸和一张瓦楞纸粘合而成的;三层纸护角也称单纸护角,是在一张面纸和一张里纸之间粘一张瓦楞纸而形成的;五层纸护角也称双纸护角,是在面纸、芯纸、里纸之间粘二张瓦楞纸而形成的;七层纸护角也称三纸护角。是在面纸、芯纸、里纸之间粘三张瓦楞纸而形成的。
The types of paper corner protectors are generally divided into single-sided paper corner protectors, three-layer paper corner protectors, five layer paper corner protectors and seven layer paper corner protectors. The single-layer paper corner protectors are formed by gluing a piece of face paper and a piece of corrugated paper; the three-layer paper corner protectors are also called single paper corner protectors, which are formed by gluing a piece of corrugated paper between a piece of face paper and a piece of inner paper; the five layer paper corner protectors are also called double paper corner protectors, which are formed by gluing a piece of face paper, core paper and inner paper Glued between two sheets of corrugated paper and formed; seven layer paper corner, also known as three paper corner. It is formed by gluing three pieces of corrugated paper between face paper, core paper and inner paper.
2、纸护角的波形选择
2. Waveform selection of paper corner protector
瓦楞波形一般分为U形、V形、UV形三种。U形楞的愣顶是圆的,V形楞的愣顶近似于三角形的顶,UV形楞的愣顶形状介于两者之间。

Corrugated wave is generally divided into U-shaped, V-shaped, UV shaped three. The U-shaped edge is round, the V-shaped edge is similar to the triangle, and the UV shaped edge is between them.
V型:又名三角形。瓦楞的峰和谷半径较小,峰谷间成直线连接,楞峰接触面小,节省粘合剂和原纸,但粘合强度,由于两条斜线的合力作用,平面抗压强度较大,但超过了它的承受力限度,
V-shape: also known as triangle. The peak and valley radius of corrugating is small, the peak and valley are connected in a straight line, the contact surface of corrugating peak is small, the adhesive and base paper are saved, but the adhesive strength is low. Due to the combined force of the two oblique lines, the plane compressive strength is larger, but it exceeds its bearing capacity,
瓦楞会迅速被破坏,压力消除后不能恢复原状,缓冲性能差,弹性小。
Corrugating will be quickly destroyed, pressure can not be restored after the elimination of the original, poor cushioning performance, small elasticity.
U型:又名圆弧形。其瓦楞均衡,由峰谷连接而成,楞峰接触面大,着胶面积大,粘接牢固,粘合强度大,由于圆弧的力点不稳定,其平面抗压强度于V型纸护角,但它的伸张、缓冲性能好,当压力消除后,瓦楞能基本恢复原状,弹性较好。
U shape: also known as arc shape. Its corrugating is balanced and connected by peaks and valleys. It has large contact surface, large adhesive area, firm adhesion and high adhesive strength. Due to the unstable force point of arc, its plane compressive strength is lower than that of V-shaped paper corner protector, but its stretching and buffering performance is good. When the pressure is eliminated, the corrugating can basically return to its original state with good elasticity.
UV型:是采取V型和U型的优点结合而成的,既保持了U型楞的粘合强度,又具备V型楞的高平面抗压强度,承受力较大,弹性也好,因此,目前广泛采用UV型瓦楞制造纸护角。
UV type: it is formed by combining the advantages of V-type and U-type. It not only maintains the adhesive strength of U-type corrugating, but also has the high plane compressive strength of V-type corrugating. It has large bearing capacity and good elasticity. Therefore, UV type corrugating is widely used to make paper corner protectors at present.
顾客对瓦楞波形一般不做要求,但在合适的条件下,为保证和提高纸护角强度,增加硬度及抗冲击力,满足弹性和印刷需要,可选择B楞为V形,C或A楞为UV形或U形结合方式。
Customers generally have no requirements for corrugating waveform, but under appropriate conditions, in order to ensure and improve the strength of paper corner protection, increase hardness and impact resistance, and meet the needs of elasticity and printing, they can choose V-shaped corrugating, UV or U-shaped combination of C or A-shaped corrugating.
