100% FSC Paper UN3373 Envelope
Traditional Plastic Bubble-Lined UN3373 Envelope
What is the optimal choice – paper or plastic?
Regulatory Compliance (ADR P650 / UN3373)
Fully compliant rigid outer packaging when used in triple‑layer P650 system; meets UN3373 marking, drop‑test performance, humidity and vibration requirements.
Typically compliant when used with certified secondary packaging; widely used in UN3373 workflows in road and postal systems.
Equal
Material Composition
Six layers of FSC‑certified kraft paper (75/75/100/100/75/75gsm) designed for strength and rigidity.
Made of LDPE plastic with internal bubble padding; multi‑material construction makes recycling difficult.
100% paper
Recyclability / Environmental Impact
100% paper; easy to recycle; significantly lower CO₂ footprint; uses Nordic Swan‑certified inks and climate‑neutral production options.
Hard to recycle due to mixed materials; usually ends as clinical or residual waste; higher environmental burden.
100% paper
Waste Sorting
Can be disposed of directly in paper waste if uncontaminated.
Must be separated into plastic and paper — practically impossible — and is usually incinerated.
100% paper
Perceived Sustainability
Strong positive sustainability signal; aligns with healthcare sector climate goals.
Perceived as less environmentally responsible; plastic is increasingly discouraged.
100% paper
Resource Consumption in Production
Lower CO₂ emissions and reduced water/energy usage due to paper‑based materials.
Plastic requires fossil resources and higher energy input during manufacturing.
100% paper
Structural Durability
Reinforced side folds, folded bottom, uniform paper layering for high durability; performs strongly in postal logistics.
Bubble padding provides cushioning, but bubbles can burst; bottom seams are often glued or heat‑sealed with uneven protection.
Equal
Water Resistance
Embossed kraftliner provides moderate to high moisture resistance; samples remained dry after UN3373 approval water‑exposure test.
Naturally water‑resistant due to LDPE surface.
Bubble-plastic
Shock Protection / Padding
Paper cushioning from multi‑layer structure provides good mechanical protection.
Bubble layer offers strong impact protection.
Equal
Noise During Handling
Quiet and smooth handling; noise‑free when packed or opened.
Plastic bubble envelopes can produce noise during handling.
100% paper
Weight
Slightly heavier but still lightweight for postal systems.
Very lightweight, low postage impact.
Bubble-plastic
Ease of Use
Easy opening/closing; compatible with self‑adhesive closures; rigid design simplifies packing.
Easy to open/close; flexible structure; widely familiar in mailrooms.
Equal
Signal Value to Patients & Clinics
Clearly communicates environmental responsibility; supports ESG and green‑procurement policies.
Often viewed as outdated and environmentally unfriendly.
100% paper
Fit Within Healthcare Logistics
Ideal for hospitals, clinics, labs, screening programs and sustainability‑focused procurement; reduces clinical waste volume and cost.
Common in clinical workflows prioritizing cushioning; increasingly challenged by environmental requirements.
100% paper
Purchase cost
Slightly higher unit price due to material quality and sustainable production.
Often cheaper at purchase price but higher lifecycle waste cost.
Bubble-plastic
Lifecycle cost CO2
Preliminary estimates indicate CO2 emission is reduced by 75%, when using recyclable 100% paper-based envelopes*
As material separation is impossible, the single-use process is estimated to have a high level of CO2 emission*
100% paper
Waste handling EURO
Preliminary estimates indicate cost of waste handling is reduced by 90%, when using recyclable 100% paper-based envelopes*
As material separation is impossible, the single-use process is estimated to have a high level og waste cost. (EU levies on plastic fraction included)
