Sheet corrugated board
Sheet corrugated board
By purchasing corrugated board - you get a convenient, simple and practical material for packaging various goods. The use of available materials in production makes it particularly attractive in price. Corrugated cardboard can be used for storage, transportation and stacking (warehousing) of goods in a convenient form.
Benefits of corrugated board
Today corrugated board is the most widespread universal packaging material in the world. Differs in low weight and low cost with good physical parameters. Another feature of its production is paper and cardboard obtained from renewable sources: cellulose and waste paper. Disposal of used corrugated board does not harm the environment.
Corrugated packaging and products are versatile and suitable for food, non-food and healthcare applications. Convenient packaging provides the hygiene, reliability and durability required for transporting goods.
Corrugated board consists of alternating flat and corrugated layers glued along the line of contact between the top and bottom surfaces of the corrugation wave and flat layers of cardboard and paper. Corrugated cardboard refers to materials that have different properties in both directions. It provides sufficient plane and end rigidity and shock absorption properties. A corrugated cardboard layer, when forces are applied perpendicular to the corrugation, acts as a shock-absorbing material, when forces are applied along the direction of the corrugation, as a rigid material.
Thus, corrugated board has the following important advantages:
- Natural materials
Corrugated board classification
Corrugated cardboard is classified according to the number of layers of paper used for the manufacture of corrugated cardboard sheets and marked with letters corresponding to the number of layers:
- D - two-layer corrugated board , consists of one flat layer and one corrugated
- T - three-layer corrugated board , consists of two flat layers and one corrugated
- P - five-layer corrugated board , consists of three flat (two outer, one inner) and two corrugated layers
Corrugated board profiles
A characteristic feature of corrugated cardboard is the presence of a corrugated (wavy) layer. Corrugated board consists of alternating flat and corrugated layers glued along the line of contact between the top and bottom surfaces of the corrugated wave and flat cardboard layers.
The defining indicators characterizing the types of corrugations are the height of the corrugation and the step of the corrugation. The height of the corrugation is the distance between its lower and upper points. Corrugation step - the distance between two adjacent upper corrugation points. A certain combination of indicators (height and pitch of the corrugation) is called a profile.
Currently, there are three types of corrugated board profiles:
- Profile E (micro-corrugated cardboard), profile height 1.1-1.6 mm
- Profile B, profile height 2.2-3.2 mm
- Profile C, profile height 3.3-4.5 mm
The main purposes of the profiles of three-layer corrugated board
Corrugated board with profile C is intended for the manufacture of boxes and containers for transportation and storage of products (high strength when stacking).
Corrugated board with B profile is intended for the manufacture of boxes, containers and trays for transportation and storage of products (medium strength when stacking, good printable surface).
E-profile corrugated board is intended for small package sizes (low stacking strength, very good printable surface).
The main purposes of the profiles of the five-layer corrugated board
Corrugated board with the BC profile is intended for the manufacture of boxes and containers for heavy items requiring high protection (very high strength when stacking, high impact resistance).
Corrugated board with EU profile is intended for the production of boxes and containers for heavy items requiring high protection (high stacking strength, high impact resistance, good print surface).
