Biodegradable Series

The Future of Responsible Packaging

A new generation of biodegradable drinking straws — products that perform like conventional straws but are designed to fully biodegrade in the natural environment.

Our biodegradable straws are manufactured using Polymateria’s Lyfecycle™ biotransformation technology — a revolutionary approach that ensures plastic can fully biodegrade in the natural environment without leaving microplastics behind.

Recyclable
Conventional recycling streams accept our product like any other PP item.
Time-Set Biodegradation
A predictable timeline from disposal to biotransformation — no surprises in storage.
No Microplastic
Full biodegradation leaves no plastic fragments behind.
No Toxin
No toxic chemistry introduced to the material or the environment.
1

In Use

During product use, the technology is dormant. Full functionality retained. Shelf life up to 2 years when stored correctly.

2

After Disposal

Exposed to the natural environment, the material converts into a bioavailable wax — no longer a plastic.

3

Fully Biodegraded

Natural bacteria and fungi break the wax down completely. No microplastics remain.

Our Story

Nearly three decades of straws, every one to the same standard.

Weng Xiang Plastic Sdn Bhd was founded in 1997 by Vincent Lim, who left a career in banking to pursue a simple belief: that quality matters in every detail — even the straw in your drink.

What began as a three-person operation with a single production line has grown steadily through nearly three decades of dedicated work. Today, Weng Xiang operates multiple production lines with a workforce of up to 20 people and the capacity to produce up to 60 million straws per month.

Over the years, we have expanded from traditional roll-packed straws into auto-packed, individually wrapped, and specialty products — consistently investing in automation to deliver better quality and reliability to our customers.

Our products reach every corner of Malaysia — and beyond — through a trusted network of distributors and direct partnerships. We are proud to supply the market under our own Twin Dolphins® brand, a name that has become synonymous with consistent quality in the Malaysian drinking straw industry.

Now, we are taking the next step. By incorporating Polymateria’s biotransformation technology, we are introducing a new generation of biodegradable straws — products that perform like conventional straws but are designed to fully biodegrade in the natural environment, leaving no microplastics behind.

From a single production line to a modern manufacturing facility — our commitment remains the same: deliver quality products that our customers can depend on, every time.
