Nubifil is made for envelope, bag and mailer converters. It runs on your existing converting lines and cuts material cost by 30 to 50 percent.
For converters currently using Tyvek® material, the table below provides reference points for selecting Nubifil samples. Nubifil is an independent product, and final suitability should be confirmed on your own equipment.

Banks, law firms and hospitals pay for envelopes that protect contents and look official. Nubifil holds crisp print, stays stiff in the hand, and tears only when someone means to tear it, exactly the tamper signal security mail needs.
Recommended grades50 gsm hard · 80 gsm hard · 100 gsm hard
Retail brands choose this material because it looks like paper but outlives it. Nubifil sews and heat seals cleanly, keeps its shape on the shelf, and stays recyclable where laminated paper bags cannot.
Recommended grades45 gsm soft · 60 gsm soft · 70 gsm soft


A mailer survives sorting machines, rain and rough handling only if the material does. Nubifil gives you tear resistance paper cannot reach, full waterproofing, and lower weight that cuts postage on every piece.
For padded lines, Nubifil laminates with bubble cushioning. And unlike plastic PE mailers, it is recyclable as #2 HDPE.
Recommended grades80 gsm hard · 45/60 gsm soft for laminated constructions
More ways converters run Nubifil
One material supplier can cover all of them: one validation process instead of many, and no duplicate inventory. Also producing drawstring pouches, security pouches or gift wraps? Send us the product, and we will tell you which grade fits.
Custom printed colors
Nubifil starts as a white flashspun HDPE sheet. For packaging that needs a different look, we can add full-surface printing in gold, silver and other custom colors. Several customers already source custom-printed material from us for finished packaging.
Color is printed on the white base rather than dyed through. Send us a color reference for sampling.
30–50%
Nubifil sells factory direct. Most converters cut their material cost by 30 to 50 percent after switching.
5–7 days
Standard orders ship from our own plant in 5 to 7 days. Your production schedule stops depending on a distant supplier's queue.
300 m²
Our minimum order starts at 300 square meters. A trial order fits a 20-person workshop as easily as a 200-person factory.
Free
We send free sample rolls, 1.6 meters wide or slit to your required width. Print, die cut and seal it on your own equipment before you spend anything.
| Item | Range |
|---|---|
| Basis weight | 45-120 gsm |
| Thickness | 0.13-0.28 mm |
| Roll width | 1,600 mm standard, slit to your required width |
| Structure | Hard structure / point-bonded soft structure |
| Surface treatment | Corona, antistatic, softened (per grade) |
| Color | White base; gold, silver and custom colors available through surface printing |
| Printing compatibility | Flexography, gravure, digital (HP Indigo, inkjet), thermal transfer, screen printing, offset |
One method to avoid: laser printing. The material softens around 80°C, so laser fusers can damage it.

Payment is simple: T/T in advance, with no minimum order value.

Production line

Quality control & warehouse
Nubifil is a flashspun nonwoven made from 100% high-density polyethylene. It belongs to the same material class as spunbonded olefin papers used for premium envelopes and mailers.
Use the reference table above as a starting point, then confirm the result with a sample trial on your equipment. Nubifil is an independent product and is not represented as identical to another manufacturer's material.
Buying directly from the manufacturer can reduce distribution markups and simplify sourcing. Actual savings depend on grade, quantity, destination and current supplier pricing.
Yes. Hard-structure grades from 50 to 120 gsm cover envelopes, labels and courier bags; soft-structure grades from 45 to 70 gsm cover tote and laminated bags. The grade reference table above maps each style to its typical use.
Yes. Gold, silver and other custom-color versions are produced by printing on the white base material rather than dyeing the material through. Send us your target color or reference sample so we can confirm the printing result.
Our MOQ starts at 300 square meters. That is small enough for a trial run on a single machine.
Standard orders ship in 5 to 7 days after payment. Delivery time then depends on your destination and shipping method.
Yes. Sample rolls are free, available at 1.6 meters wide or slit to your required width.
Yes. Nubifil laminates with PE film and bubble cushioning, which makes it suitable for padded courier mailers.
Flexo, gravure, HP Indigo, inkjet, thermal transfer, screen and offset printing all work. Laser printing does not, because fuser heat exceeds the material's softening point.
We work T/T in advance. There is no minimum order value.
Samples are free and ship from stock. Tell us the style you run today, and we will send the matching grade.
We will prepare your sample roll and get back to you shortly.
