Product FAQs

What is LDPE plastic?

Low-density polyethylene (LDPE) plastic is very flexible, translucent and lightweight, making it a popular choice for multipacking canned beverages. Traditionally, LDPE rings are widely considered to be one of the most affordable types of multipack packaging.

Roberts PolyPro manufactures Grip-Pak® LDPE can rings, which are certified 100% biodegradable.

What is HDPE plastic?

High-density polyethylene (HDPE) plastic is rigid and sturdy, making it a great choice for canned beverage and bottle carriers. HDPE multipack carriers effectively hold the products in place, while still offering easy removal and the opportunity to reuse the handle.

Roberts PolyPro manufactures Craft-Pak® HDPE carriers, which use up to 30% less plastic than other leading HDPE carriers and are 100% recyclable.

All other Roberts PolyPro HDPE plastic products — including bottle handles, hook and hanger solutions and more — are also 100% recyclable.

What’s the difference between LDPE and HDPE multipack carriers?

While both LDPE and HDPE multipack carriers are made with plastic, they have some distinct differences:

  • HDPE carriers are the go-to choice for making products stand out on shelves with their color customizability. These are a great option for companies who would like to design the top of their can carriers, or simply want a more attractive packaging option.

  • LDPE is a convenient, standard option for those who need something lightweight and simple but don’t need the attractiveness of color as a point of differentiation for packaging.

Roberts PolyPro offers LDPE and HDPE handle solutions designed to accommodate a wide array of cans and bottles for beverages.

How do your prices compare to other alternative solutions?

Customers who switch to Roberts PolyPro’s Craft-Pak® can carriers typically save up to 25%, or .03¢ to .05¢, per 4- and 6-pack compared to other HDPE plastic solutions. That’s over $6,500 in cost savings for customers who purchase 120,000 units per year.

This same savings applies to Robert’s PolyPro bottle handles – customers can save up to 25% over competitor HDPE plastic handles.

Additionally, averaging only 5¢ per unit, our Grip-Pak® can carriers have been the affordable go-to choice for multipacking canned beverages for over 30 years.

Connect with our team today to discuss how much you could save by switching to our can carrier, bottle handle, or hook and hanger products.

Are your products customizable?

Roberts PolyPro offers custom packaging solutions and equipment. In fact, many of the plastic solutions we now offer started as a custom project for one of our clients. Whatever your needs, the chances are good that we either have or can design a solution to fit those needs. Learn more about our custom plastic solutions here.

How do I remove a can from Roberts PolyPro’s 6-pack can carrier?

Our Craft-Pak can handles are equipped with an open-ring design and patented t-tabs that hold cans securely. To release a single can without tugging or struggling, simply lift the two t-tabs on the carrier handle. Learn more by watching this video.

How do I remove a bottle from Roberts Polypro’s bottle carrier?

Our HDPE bottle handles and carriers are made to hold bottles securely until you’re ready to consume them. To release a single bottle without struggling, simply lift the single tab upwards. Learn more by watching this video.

Sustainability FAQs

How is sustainability ingrained into your company?

At Roberts PolyPro, each of our products, processes and solutions are intentionally designed to minimize environmental impact.

From the raw materials that make up our products to the time our products are discarded by your end user, we strive to make greener choices throughout the entire product lifecycle for future generations and their well-being. Learn more about our sustainability commitment here.

Is plastic packaging bad for the environment?

While all packaging and production of goods cause some strain on the environment, reducing that impact is important. With that said, plastic packaging is not always detrimental to the environment, depending on the materials used to create and distribute it. Newer paper-based and plant-based multipacks are generally perceived as more sustainable by the public, but their overall environmental impact can be more harmful.

Roberts PolyPro is always investing in better ways to meet our customers’ packaging needs while making as small an impact on the environment as possible.

All Roberts PolyPro products are made with 100% recyclable plastic, produce near-zero waste and require 75% less space for shipping and storage due to their unique design. This means less gas and fewer trucks to ship products.

Does Roberts PolyPro have a zero-waste manufacturing process?

Roberts PolyPro recaptures scrap plastics and resins to create post-industrial regrind (PIR). The PIR is then reintroduced into the production process, enabling a closed-loop manufacturing system. This makes the facility near-zero waste — a win for sustainability and the environment.

Roberts PolyPro uses this plastic regrind process to manufacture all of our packaging products.

Which of your products are biodegradable?

It takes a standard 6-pack plastic ring an estimated 400 years to decompose¹. That’s why we’ve developed our Grip-Pak® product line of flexible, low-density polyethylene (LDPE) multipack can rings to be certifiably 100% biodegradable, completely degrading within months², not years.

We’re working to ensure the same product performance certification will be awarded to our full product line by 2025, including all high-density polyethylene (HDPE) handle options for bottles and cans.

What’s the difference between photodegradable vs compostable vs biodegradable?

Photodegradable materials use a polymer that is broken down when exposed to UV light – but only when exposed to light, which generally doesn’t happen in a landfill environment.

Compostable materials are eco-friendly, plant- or fiber-based and will break down completely over time — but only under certain conditions.

Biodegradable materials break down naturally in landfill conditions, causing less harm to the environment. Biodegradability may vary depending on temperature, moisture level, presence of UV light, or other external conditions.

Learn more about these processes and how they relate to can carriers in this blog.

How do your products contribute to minimizing packaging waste?

For over 15 years, we have implemented lean design and manufacturing methodologies to reduce waste and improve line and machine utilization. Our product design uses up to 30% less plastic than competing plastic products.

Any scrap material resulting from the creation of our plastic products is reused as post-industrial regrind (PIR). This enables a closed-loop manufacturing process, produces near-zero waste, lowers the amount of plastic being sent to landfills, and emits fewer transport emissions compared to the use of recycled plastics.


²Following a rigorous 28-week scientific test, an independent agency demonstrated that our Grip-Pak® can rings completely biodegraded, without any false-positives or false-negatives.
