Angle bracket made of solid cardboard profile V 45x45x3mm length 1100mm

Cardboard corner 45×45×3 mm, length 1100 mm - Universal protective pillar for high loads 📦

Three millimeters of solid cardboard on each side of the profile create a solid shield protecting the edges of pallet loads from crushing, friction, and film cutting. The 45 × 45 mm arms evenly distribute the pressure of strapping tapes and the weight of stacked pallets, minimizing point damage. Extra-long 1100 mm protects virtually the entire height of a standard EUR pallet, so a high stack of boxes maintains rigidity from the base to the top layer. One piece weighs just ≈ 0.195 kg, and the natural brown (KRAFT paper) emphasizes the environmentally friendly nature of the packaging. Ideal for the electronics/appliances, furniture, chemical, and FMCG industries ⭐.

The 45 mm profile withstands the pressures of 15-19 mm PET tape (up to 900 N) and allows safe stacking of pallets with boxes with a total weight > 800 kg. In combination with PE foam sheets and cardboard inserts, it creates a modular packaging system reducing the number of complaints by even 70 %.

What is a solid cardboard corner?

Cardboard corner is a protective profile in the shape of the letter "L", covering two planes of the package and the corner itself. The 3 × 45 × 45 mm version combines a relatively small arm width with a length of 1100 mm, creating a lightweight, but very rigid frame. Multi-layered solid cardboard dissipates compressive forces during strapping, forklift transport, and pallet stacking. The profile protects both delicate cardboard boxes and granulate bags or wood-based boards.

The installation takes a few seconds: set the profiles in the corners, wrap with stretch film and tighten the belt. After unloading, the corners can be disassembled, stacked and reused or recycled.

Material - solid cardboard (KRAFT)

The profile is made of glued layers of high-density KRAFT paper. Laminating sheets at a 90° angle creates a beam resistant to compression and bending, yet lightweight and 100% biodegradable.

• Composition: 100% cellulose fibers - no plastic, VOCs or heavy metals.
• Layered construction: 10-11 sheets of chemically pressed paper to a thickness of 3 mm.
• Crush resistance: Edge Crush > 400 N - no deformation with a 900 N tensioned tape.
• Neutrality: odorless, chemically neutral - safe in indirect contact with food.
• Optional finishes: PE hydrophobic coating, antistatic varnish, CMYK print.

🛡️ Corner properties - protection & rigidity

• 🛡️ Full 360° protection: 45 mm arms protect corners to a full height of 1100 mm.
• 📏 Pressure dispersion: eliminates point dents when tensioning the tape and pressing the top pallet.
• 🏗️ Column stabilization: prevents high boxes and bags from wobbling.
• 🔄 Reusability: retains shape after ≥ 8 logistics cycles.
• ⚖️ Optimal weight-strength ratio: 0.195 kg is less than 0.25 % of the average RTV pallet weight.

Resistance to external factors

• 💧 Humidity: paper absorbs water; PE coating reduces absorption to < 1 %.
• 🧪 Chemicals: neutral to most goods; PE coating protects against oils and greases.
• 🌡️ Temperature: stable from −25 °C to +75 °C – does not crumble or soften.
• 🔥 Flammability: class B2 – self-extinguishing when flame is removed.
• ⚡ Antistatic: no ESD charges – safe with steel tapes.

🚚 Applications in transport and logistics

• RTV/AGD - refrigerators, freezers, 65-85ʺ televisions in high cartons.
• Furniture - packages of wardrobes, countertops and panels 1100 mm high.
• Bags of granules, pellets, feeds - columns of bags secured to full height.
• FMCG - packs of drinks and food products on half-pallets.
• OSB, MDF, HDF boards - edge protection with 16–19 mm steel straps.

🏭 Industries using 45 mm x 1100 mm corners

• Electronics & premium appliances 📺🧊 - manufacturers of large televisions and refrigerators protect high cartons from crushing during stacking and long hauls.
• DIY Furniture & retail 🛋️🛠️ - profiles stabilize packages of furniture boards and shelves packed vertically, reducing edge damage.
• Granules & pellet 🔥🌾 - pellet and feed producers use 1100 mm to prevent the column of bags from cracking when stretching the stretch film.
• 3PL / Fulfilment XL 🚚💼 - operators consolidate diverse loads on mix-pallets, using long corners as universal reinforcements.
• DIY & building materials 🪵🏗️ - OSB/MDF board wholesalers and DIY markets protect the edges of packages when strapping with steel tape.
• POS & retail merchandising 🏬🎨 - exhibition agencies reinforce pallet displays with drinks and seasonal items.

💰 Logistic and economic benefits

• 💸 Low unit cost: several times cheaper than a plastic corner of comparable size.
• ⚖️ Low weight: 0.195 kg/piece does not increase freight charges.
• 📐 Nest storage: 600 pcs. = 0.5 m³ of storage space.
• ⏱️ Faster packing: no gluing and cutting foam - cycle time +18 %.
• 🔄 Re-use 8–10×: in the closed loop of returnable pallets.
• 📉 Claims -70% - data from RTV/AGD customers 2024.

⚙️ Cardboard corner production process

On the BÖWE RollCorner line, KRAFT tapes are glued with PVA-D3 adhesive, wrapped at a 90° angle, pressed 4 t/m and dried at 80 °C. The "V" profile of 45 mm is stabilized for 12 hours, after which it is cut with a laser guillotine into exact sections of 1100 mm. Each batch undergoes an ECT test > 400 N, humidity measurement and 3D angle scan ±0.4°.

🏆 Advantages of cardboard corners in bulk packaging

• 🛡️ Protection 4 × 1100 mm – full corner protection.
• 📦 Pallet stability – no wobbling in the high storage warehouse.
• 🏗️ Stacking 1 + 1 – the top pallet does not crush the bottom one.
• ⏱️ Line rhythm +18 % – "click & wrap" assembly.
• 💰 ROI < 1 cycle – cost recovers by avoiding one damage.
• 🌱 Zero micro-plastics – 100% recyclable material.

♻️ Recycling and ecology

The corner goes to the PAP 20 fraction. In the paper mill, fibers and thermal energy from glue are recovered. If the profile is dirty (e.g., with plaster), it can be burned in an energy recovery boiler – it emits only CO₂ and steam.
