About us

It all started as a project to create a fun gift for one of our REDSTAR WORKS design studio clients. I was looking for an interesting material and I fell in love with TYVEK. It looks like paper but it is stronger, waterproof and tear resistant. Tyvek material develops a certain patina when it ages, almost like leather would, adding a vintage feeling to the bags.
I loved the idea of a lunch bag with Chinese characters on it and decided to do a run, which we could give away as gifts. But as soon as I showed the bag with the 吃饭了!(Lunch in Chinese, or let's eat) my friends wanted to buy them as gifts to take back home. Then I wanted to use the material to make a bag, that looked nice, didn't cost an arm and a leg, and was great for everyday wear and shopping, something that will fit quite a few things and still look nice. I then added a wine bottle cooler bag to the range of products, because its a fun way to gift a bottle of wine or take a chilled bottle of wine to a picnic. 
This is how RS.Works was born. 
You can find our products now in stores in China, Bulgaria and UK or online on our website.

Thank you all for your support.

Tyvek /tˈvɛk/ is a brand of flash spun high-density polyethylene fibres, a synthetic material; the name is a registered trademark of DuPont. It is often seen used as housewrap, a synthetic material used to protect buildings during construction. The material is very strong; it is difficult to tear but can easily be cut with scissors or a knife. Water vapour can pass through Tyvek, but liquid water cannot. All of these properties make Tyvek useful in a variety of applications.


Tyvek's properties:

  • Light weight
  • Class 1 flammability rating
  • Chemical resistance
  • Dimensional stability
  • Opacity
  • Neutral pH
  • Tear resistance



Mechanical recycling

Being 100% HDPE, Tyvek® or products made from Tyvek® can be mechanically recycled into products such as underground cable protection piping, automotive parts, blown film, packaging cores and flowerpots. Products made from Tyvek® which are printed, glued, welded or sewn can also be recycled as can Tyvek® which has been extrusion coated or laminated with a polymer of the same family. Polyethylene can normally be recycled 4 to 5 times before physical properties are substantially affected. Chemical feedstock recycling Tyvek® can be chemically recycled with other polymers. In this process the original material is separated into its chemical components, which are then recovered for reuse.

Energy recovery

When incinerated in excess oxygen Tyvek® yields only water and CO2 . It is excellent in fuel yielding: two or more times the energy of coal, and is equal to oil in generating heat. Incineration of HDPE does not contribute to acid rain.


Whilst DuPont does not encourage landfill, Tyvek® can, as a last resort, be safely disposed of in this way. It will not leach into groundwater because it is chemical inert and doesn’t contain binders, fillers and plasticizers.

Where to recycle Tyvek® at the end of their useful life, products made from Tyvek® can be recycled via your local recycler for polyethylene waste. Additionally DuPont has set up a network of recyclers who have agreed to take back items made from Tyvek® for mechanical recycling into other products. 

For small quantities (less than 25), stuff them in an inside-out Tyvek envelope and mail them to:
