Honeycomb Cardboard Sheet 600x400x30

"Honeycomb" Cardboard Sheet 600 × 400 × 30 mm - Maximum Thickness, Maximum Protection

"Honeycomb" paper construction - hexagonal core cells + precisely selected cover layers - creates an light, yet exceptionally rigid board resistant to crushing and impacts. The material is more than eight times lighter than wood, and after use it goes directly into the waste paper stream. The 600 × 400 × 30 mm format is perfect as an insert, filler or spacer in the transport of heavy and sensitive loads.

🍯 What exactly is a "honeycomb" structure sheet?

Honeycomb sheet is created in three steps:

1. Core expansion – Kraft paper strips are alternately glued with strips of water glue, rolled into a block, and then "stretched" lengthwise, forming a rigid network of hexagonal cells with a height of 30 mm.
2. Lamination of the coverings – the faces of testliner (durable recycled paper) are applied to both sides of the core, which transfer tensile and compressive stresses like the straps of a double T-beam.
3. Cutting to size – the finished plate is laser cut or cut with a tape knife to the dimension of 600 × 400 mm.

• 🔬 Base material: 100% kraft paper (recycling) + water glue without solvent.
• 🪶 Surface mass (30 mm): approx. 1.35 kg/m² — over 30% lighter than 30 kg/m³ PE foam.
• 📊 Core parameters: height 30 mm · mesh 15 mm · wall thickness 0.2 mm.
• 🌍 Ecology: fully biodegradable, compostable and recyclable in the waste paper stream.

🧪 Key properties – stiffness + damping

This sheet combines the hardness of the board and the "spring" of the foam, therefore it protects goods equally well from slow crushing in the warehouse as well as from sudden shocks during transport.

• 🏋️‍♂️ Reliable protection when stacking – withstands pressure up to 1 600 kg / m², so your pallets will not flatten even on the lowest layer.
• 📏 Less distortion – stiffness 95% higher than in PE foams means less crushing and complaints.
• 💥 Shock absorbing – absorbs the energy of a fall from 1.2 m, protecting fragile glass, ceramics or electronics.
• 🔄 Multiple uses – after removing the load, it recovers up to 85% of its thickness in 30 s, so you can use it again.
• 🪶 Light as a feather – weighs only 1.35 kg / m²; this reduces the freight cost and reduces the CO₂ footprint compared to wooden inserts.

The effect? One sheet replaces both the wooden board and the PE foam, simplifying packaging and saving money.

• 🌡️ From frost to heat – maintains parameters from −20 °C to +70 °C, so it will work in a cold store and on a heated ramp.
• 🌧️ Not afraid of moisture – short-term dampening does not lower the stiffness of the sheet; the material is not intended for constant, continuous exposure to water.
• ⚡ Electronics-friendly – the antistatic version dissipates charges, protecting sensitive components from "dry shorting".
• 🍏 Food contact (indirect) – paper and starch glue do not transfer tastes or odors; lack of certificate for direct contact.
• 🔥 Easy disposal – after recycling, it can be burned to recover energy, without smoke and toxic ashes.

📦 Typical applications – how you can benefit

• 📑 Pallet pads and layers - the sheet distributes the weight over the entire surface, allowing you to stack boxes higher and use up to 30% more space in the warehouse.
• 🔄 Filling empty spaces – after quick cutting or scoring, you create wedges and 3D dividers that immobilize the goods and prevent bruising.
• 🫧 Protection of delicate surfaces – wrapped around glasses, photovoltaic panels or paintings, it prevents scratches and absorbs shocks without dusting.
• 🛡️ Paper corners and angles – protect furniture, monitor frames, and furniture boards, and end up in waste paper after use.
• 📦 E-commerce package insert - lightweight sheets create a "nest" for porcelain, candles or audio equipment; the customer receives a package free from styrofoam and easy to recycle.
• 🏗️ Lightweight POS construction boards – you build trade stands up to 2.4 m; tool-less assembly, and transport is one-third cheaper.
• 🪑 Plug-and-play furniture – filling countertops and fronts reduces the weight of the furniture by 35%, facilitating assembly and reducing shipping costs.

🏭 Industries that are already using honeycomb cardboard - and why

• 💻 Electronics & optics – sheets separate matrices, PCBs and LED modules, preventing scratches and ESD discharges with minimal increase in shipment weight.
• 🚗 Automotive – paper boards protect glass sheets, body parts and interior parts; reduce cracking during transport, and after unloading they go directly to paper recycling.
• 🛋️ Furniture & interior decoration – used as a filling for countertops, doors and panels; lower the weight of the furniture by up to 35%, simplifying assembly and reducing shipping costs.
• 🍶 Premium food and beverage industry – honeycomb formats create cushioning nests for bottles and jars, combining the aesthetics of "eco-look" with easy recycling for the customer.
• 🧴 Pharmacy & cosmetics – used as a lightweight 2-8°C insulation insert in refrigeration packaging; after delivery, the consumer throws the material into the waste paper container.
• 🎨 POS & advertising – from the boards are created stands and display walls up to 2.4 m; the constructions are so light that one person assembles them without tools in a few minutes.

♻️ Recycling and reuse – closing the loop

The honeycomb sheet is 100% homogeneous paper, so "cleaning" after it is as simple as throwing away a newspaper.

• 🗑️ Sorting without guessing - throw it into the blue bin along with cardboard and newspapers; no need to separate any foils or foam.
• ♻️ Full loop closure - paper mills process it into new corrugated cardboard or newspaper, reducing the cutting of fresh trees.
• 🔄 Second life in the warehouse - thanks to the recovery of thickness, you can use the same sheet several times as inserts or fillers.
• 🌱 Compost option - if it ends up in BIO waste in an industrial installation, it decomposes within a few weeks, turning into natural humus.
• 🔥 Energy without toxins - when recycling is not possible, paper burns cleanly (< 1% ash), recovering heat instead of lingering in a landfill.

📦 Custom-sized boxes and packaging personalization

Match a custom-sized box to the honeycomb sheet - you'll get a perfect duo of protection and ecology.

• 🔒 Zero slack - format + box eliminate empty spaces, so the goods don't "fly" inside.
• 🌍 Zero plastic - one stream of waste paper at the customer's.
• 💡 Effective branding - inside/outside print + natural paper look.
• 📦 Less volume = lower costs - compact packages → cheaper freight.
• ♻️ One waste fraction - simpler sorting and higher recovery.

Take advantage of Custom-sized Boxes or add a logo with Boxes with Print - your products will gain premium class protection and an eco-image.
