1. Lightweight: Plastic cans are significantly lighter than traditional aluminum cans, which means they are easier to transport and ship. This not only helps reduce shipping costs, but also reduces the carbon footprint of the beer industry.

2. Durable: Plastic cans are much more durable than traditional aluminum cans, which means they are less likely to get damaged during shipping. This is especially important for craft breweries that are shipping their beer long distances.

3. No metallic taste: One of the biggest complaints of aluminum cans is that they can leave a metallic taste in the beer. Plastic cans, on the other hand, do not have this issue. This means that the flavor of the beer is not affected by the packaging.

4. Easy to recycle: Plastic cans are easy to recycle, just like traditional aluminum cans. This means that beer drinkers can feel good about disposing of their empty cans in an eco-friendly way.

Overall, plastic cans have many advantages over traditional aluminum cans, and are a great choice for beer packaging. Not only are they lightweight and durable, but they also don't leave a metallic taste in the beer, and are easy to recycle.
