瓦楞纸板基础知识

瓦楞纸板基础知识

WHAT ISTHE CORRUGATED?Corrugated fiberboard or "combined board" has two main components: the liner (面纸)and the medium (芯纸). Both are made of a special kind of heavy paper called containerboard (箱板纸).Linerboard (瓦楞纸箱外层的高强箱板纸) is the flat facing that adheres to the medium. The medium is the wavy, fluted paper (楞纸) in between the liners.COMMON BOARD STYLES 常用纸板的种类Single Face: One medium is glued to one flatsheet of linerboard.单面纸板:一层芯纸粘接在一层平面箱板纸上。

Single Wall: The medium is between two sheetsof linerboard. Also known as Double Face.单瓦楞纸板:芯纸粘在二层箱板纸之间,也被称为双层纸板。

Double Wall: Threesheets of linerboard with twomediums in between.双瓦楞纸板:二层芯纸夹在三层面纸之间。

(在中国又被称为五层瓦楞纸板)Triple Wall: Four sheets of linerboard with threemediums in between.三瓦楞纸板:三层芯纸夹在四层面纸之间。

(在中国又被称为7层瓦楞纸板)Flutes 楞形Architects have known for thousands of years that an arch (拱) with the proper curve (曲线) is the strongest way to span a given space (跨越一个给定的空间). The inventors of corrugated fiberboard applied this same principle to paper when they put arches in thecorrugated medium(瓦楞芯纸). These arches are known as flutes (楞)and when anchored to the linerboard with adhesive, they resist bending and pressure from alldirections.When a piece of combined board is placed on its end, the arches form rigid columns, capable of supporting a great deal of weight. When pressure is applied to the side ofthe board, the space in between the flutes acts as a cushion(垫子)to protect the container's contents. The flutes also serve as an insulator (绝缘体, 绝热器,保温层), providing some product protection from sudden temperature changes. At the same time, the vertical linerboard provides even more strength and protects the flutes from damage.Flutes come in several standard shapes or flute profiles (A, B, C, E, F, etc.). A-flute (A楞)was the first to be developed. B-flute was the next and is much smaller than A-flute. C-flute followed and is between A and B in size. It is also the most common large flute profile. E-flute is smaller than B and F-flute is smaller yet. Due to variances in flute sizes between manufacturers, FBA no longer publishes flute guidelines.In addition to these five most common profiles, new flute profiles—both larger and smaller than those listed here—are being created for more specialized boards. Generally, larger flute profiles deliver greater vertical compression strength (垂直压力)and cushioning, while smaller profiles provide better resistance to process and printing crush.Different flute profiles can be combined in one piece of combined board. For instance, in a triple wall board, one layer of medium might be A-flute while the other two layers might beC-flute. Mixing flute profiles in this way allows designers to manipulate the compression strength, cushioning strength (减震强度、缓冲强度) and total thickness of the combined board.Corrugated BasicsWhat is Corrugated?Corrugated boxes are easy to recognize. Corrugated ismade of paper and has an arched layer, called "fluting,"between smooth sheets, called "liner." The corrugated mostcommonly used to make boxes has one layer of flutingbetween two smooth sheets. But there are many types ofcorrugated available, each with different flute sizes andthicknesses(厚度).Corrugated is an extremely durable, versatile, economical and lightweight material used for custom-manufactured shipping containers(运输容器), packaging and point-of-purchase displays(销售展示包装,即所谓POP展示包装), in addition to numerous non-traditional applications ranging from pallets(货盘、托盘)to children's toys to furniture.Why Corrugated?Corrugated. It's not just a brown box.Corrugated is a complete, high-performance material design, manufacturing and delivery system. Corrugated is the preferred packaging material because it is:1. Durable2. Versatile3. Lightweight4. Environmentally Friendly5. High-Tech6. Customizable7. Protective8. Graphically Appealing9. Cost-EffectiveIf it's not just a cardboard box, what is it?A High-Tech Engineered Material.What may come as a big surprise to many is that the ever-present corrugated "cardboard box"is high-tech:1. Ongoing R&D (研发)programs continuously improve such characteristics asstrength-to-weight ratios(强度与重度的比率), printability, moisture barriers (潮气阻隔) and recyclability.2. Corrugated components, designs and end products are manufactured on sophisticated,automatic equipment that reduces costs and ensures consistent performance.3. The vast majority of corrugated products are designed and prototyped with advanced,computer-aided design (CAD)and manufacturing systems, providing customers with the best and most cost-effective solutions to their packaging challenges.Infinitely Customizable.Corrugated offers thousands of possible combinations of board types, flute sizes (caliper), basis weight, adhesives, treatment and coatings, including flame retardant and static control protection.Corrugated is the only rigid shipping container and packaging medium that can be cut and folded into an infinite variety of shapes and sizes and direct-printed with high-resolution color graphics (including lithography, flexography and silk screening). And corrugated is not just for displays and boxes. Other uses include low-cost, one-way recyclable pallets, retail bulk bins, and lightweight castles that children can build themselves.There are hundreds of basic designs and thousands of adaptations, each chosen on the basis of proven experience and the proposed use of the product.Corrugated is routinely custom-designed to fit specific product protection, shelf space and shipping density requirements (including inner packaging that prevents shifting).Tenaciously Protective.Corrugated combines structural rigidity with superior cushioning qualities. Containers,packages and pallets nest products in an optimally protective environment, so even heavy or fragile contents arrive undamaged.Corrugated offers excellent tear, tensile and burst strength to withstand shipping pressures. It resists impact, drop and vibration damage while offering uniform stacking and weightdistribution so the load stays put, regardless of the form of transportation.Corrugated can be designed to contain flowable, granular or loose bulk products and even hazardous materials. It is also used to ship liquids and fresh foods, with the addition ofremovable plastic or waxed liners which serve as moisture barriers.All this from a material that is lightweight, low-cost and recyclable.Graphically Appealing.Corrugated containers and packaging are mobile billboards that create product imagewherever they travel. Corrugated displays are eye-catching modular units that can be set up quickly and recycled at the end of a promotion.Corrugated is a very flexible medium that accommodates a wide range of printing options to support the end-use requirement:1. Offset lithography and rotogravure (high-volume).2. Flexography or letterpress (shorter runs)3. Silk screening (displays)4. Corrugated can be direct printed in plant or manufactured with high-end process colorgraphics.Preeminently Cost-Effective.One of the least expensive containers ever developed, the overall cost of corrugated shipping containers is usually between one percent and four percent of the value of the goods they carry.The cost of labor and tools required to produce, fill, and move the container is low. The cost of shipping is low, due to lower weights and higher fill densities than alternative packaging. The trend toward light weighting will continue to drive down shipping costs. Low raw material costs and mass production of corrugated containers makes them particularly cost-efficient.The ultimate contribution to cost reduction is when corrugated is used as an all-in-one shipping, storage, advertising and display medium - a growing trend both in warehouse and other retail stores.Environmentally Responsible.Corrugated, made from a natural renewable resource, has a great environmental record.Corrugated is frequently manufactured using high percentages of secondary fiber (including old corrugated containers, kraft, old newspapers and even straw), thereby diverting these materials from the municipal solid waste stream.In 2004, more than 24 million tons of corrugated were recovered and recycled in the U.S. -- that's 73 percent of all containerboard produced in the same year. Corrugated has the best recycling rate of any packaging material used today.In addition, the use of corrugated constructions with high-performance linerboard has led to a significant overall reduction in basis weight and a significant source reduction of raw materials.Water-based inks are now used almost exclusively for printing graphics on corrugated containers, avoiding the use of lead-based inks and solvents which pollute the air and the water used to wash down printing equipment between color changes.Box DimensionsDimensions are given in the sequence of length, width and depth. Internationally, the words length, breadth and height may be used to express these dimensions. The dimensions of a box are described based on the opening of an assembled box, which can be located on the top or the side, depending on how it is to be filled. The opening of a box is a rectangle; that is, it has two sets of parallel sides. The longer of the two sides is considered its length, the shorter of the two sides is considered its width. The side perpendicular to length and width is considered the depth of the box.Dimensions can be specified for either the inside or the outside of the box. Accurate inside dimensions must be determined to ensure the proper fit for the product being shipped or stored. At the same time, palletizing and distributing the boxes depends on the outside dimensions. The box manufacturer should be informed as to which dimension is most important to the customer.。

瓦楞纸板知识

瓦楞纸板知识瓦楞纸板是目前世界上用量最大、使用最普遍的包装材料。

瓦楞纸板也叫坑纸板,它是先将瓦楞原纸加工成瓦楞状,然后用胶粘剂由两面将表层粘合起来,使纸板中层呈空心结构,具有较高的强度、挺度、硬度、耐压、耐破、延伸性与弹性等。

瓦楞纸板产生于19世纪末期。

1871年,美国人艾伯特·琼斯最先研究将单一的瓦楞纸加贴一层衬纸后,用于灯泡、灯罩、玻璃瓶等易碎产品的包装,并第一个取得瓦楞包装技术的专利,之后经过改进,形成双面的瓦楞纸板, 现在已发展成为5层的双瓦楞、7层的三瓦楞、11层的四瓦楞纸板,强度不断提升,使用围也越来越广。

近20年来,瓦楞纸包装在我国迅猛的发展。

目前,我国已成为世界上第二大瓦楞纸板生产国和消费国,仅次于美国,产量约占世界的五分之一。

瓦楞纸板之所以得到广泛的应用,是因为它有众多优于其他包装材料的特性。

它成本低廉,可节约木材、金属等资源;它重量轻,能折叠,可以节省运输和仓储费用;它可塑性强,易于制造,可根据装物的需要进行裁切、接合;它具有刚柔兼备的保护性,可以印刷出精美的图案来美化产品;并且它易于回收再利用,无公害,符合环保的要求。

如此多的优点,促使瓦楞纸板飞速发展,日益普与,现已广泛应用于食品饮料、日用百货、玻璃瓷、电子电器等各个行业。

因此,对瓦楞纸板有一个更加深入的了解就非常必要了。

下面我们就从以下三个方面来学习。

一、瓦楞纸板的结构种类二、瓦楞纸板的生产工艺三、瓦楞纸板的性能检验我们先来看一、瓦楞纸板的结构种类瓦楞纸板是将瓦楞原纸加工成瓦楞形状后与箱纸板粘接在一起形成的多层纸板。

我们以五层双瓦楞纸板为例,先简单认识一下它的结构名称。

上面的一层叫面纸,起瓦楞的纸叫瓦楞纸或叫芯纸,夹在两瓦楞中间的纸叫中纸,也叫夹芯纸。

下面的一层也是面纸,通常叫里纸或底纸。

这里注意一下,双层以上瓦楞的纸板,挨着里纸的瓦楞波浪大一些,挨着面纸的瓦楞小一些,这是为了保证纸板表面平整,适于印刷,增加纸板层的缓冲性能,避免出现蹋楞的现象.下面我们就具体来了解瓦楞纸板的结构。

瓦楞纸板技术知识介绍


Ⅰ-2、瓦楞纸板包装容器的优点
6.包装成本的低廉性 主要材料为原纸 7.利用资源有效性 与传统木制品相比,瓦楞纸箱原纸耗用的木材只占木制品包 装的30% 8.易于回收利用性 基本原材料为原纸,使用后可以方便地回收,回收再生利用 率可达75% 9.优越的绿色环保性 使用后瓦楞纸可燃烧、无毒害、降解快、不会对环境造 成污染 10.仓储运输经济性 由于是可折叠的轻质硬体包装,可以有效利用仓位和运输 装载空间
瓦楞纸板技术 知识介绍
概 论
『包装』的定义 为在流通过程中保护产品、方便存储、促 进销售,按一定技术方法而采用的容器材料 及辅助物的总称. 在整个包装所用材料中,纸制品包装所占比 例最大,为45.25%,其它依次为玻璃、塑料、 木制品和金属材料,而在纸制品包装中,瓦楞 纸板(箱)包装又占大多数。
Ⅳ、生产线原纸选配原则
等级选配---应选用质量等级近似的瓦楞纸和箱板纸生 产纸板。 使用高等级箱板纸和低等级瓦楞纸制成的瓦楞纸板,容 易造成塌楞。 定量选配---实验表明,提高瓦楞纸的定量有利于降低成 本。 在保持强度不变的情况下,瓦楞纸定量每增加1g/m2, 则两面箱板纸也可降低1g/m2。一般箱板纸与瓦楞纸的 定量比控制在2:1比较好。 定量过高的瓦楞纸与低定量的箱板纸生产出来的瓦 楞纸板会出现表面不平整,产生明显瓦楞条纹现象,影响 外观质量和印刷效果;如果瓦楞纸定量过低,粘合后瓦楞 齿形会改变,由圆弧形变成矩形结构,影响纸形厚度、边 压强度和缓冲性能。
