What B2B Buyers Should Look for When Purchasing Corrugated Plastic

Hello there! This is Pitt, Corrugated plastic expert in Coropak.

If you’re like most B2B buyers, you’ve probably spent countless hours researching the perfect materials for your needs. When it comes to choosing corrugated plastic, the choices can be overwhelming. But worry not! As a seasoned expert in the field, I’m here to guide you through the maze. Let’s dive into the key factors you should consider to make the most informed purchase.

1. Understand the Material Specifications

Corrugated plastic, also known as corriboard, comes in various densities and thicknesses which determine its usability across different industries. For instance, a construction company might require thicker sheets for use as temporary flooring, whereas an advertising firm needs thinner, more flexible sheets for signs and displays.

Check the specifications: Always review the product specifications like density, flexibility, and durability. Here at Coropak, we offer a wide range of polypropylene sheets that can be tailored to meet specific industry needs.

2. Consider the Durability and Resilience

Durability is paramount, especially if the sheets are to be used outdoors or in harsh environments. Corrugated plastic is chemical and water-resistant, making it an excellent choice for signage and construction barriers.

Why durability matters: Opt for sheets that are UV stabilized to ensure they withstand prolonged exposure to sunlight without degrading. Our sheets at Coropak are not only durable but also lightweight, easing the logistics and handling challenges.


3. Assess the Environmental Impact

Sustainability is a buzzword for a good reason. Companies are increasingly mandated to reduce their environmental footprint, making recyclable materials like corrugated plastic a smart choice.

Eco-friendly options: Look for 100% recyclable materials. Corrugated plastic is a fantastic alternative to less environmentally friendly options like acrylic or PVC. Details about our commitment to sustainability are highlighted on our website.


4. Printing and Customization Capabilities

If your application requires printing, corrugated plastic’s surface lends itself well to adhesion. Ensure that the material you choose can be printed on with your desired techniques—whether it’s digital printing, screen printing, or even UV curing.

Customization is key: At Coropak, we provide fully customizable printing solutions to help your brand stand out. Our advanced printing technology ensures crisp, clear, and long-lasting prints.

5. Verify the Certifications

To avoid any compliance issues, especially when the material is used in sensitive environments like food packaging or medical facilities, it’s crucial to ensure that the corrugated plastic has the necessary certifications.

Look for ASTM or ISO certifications: These ensure that the material meets stringent safety and quality standards. Our products at Coropak meet these standards, providing you with peace of mind.

6. Evaluate the Supplier Reliability

Last but not least, the reliability of your corrugated plastic supplier plays a critical role in your operational efficiency. A supplier like Coropak, which guarantees short lead times and high-quality customer service, can significantly enhance your supply chain stability.

Supplier strengths to consider: Fast delivery times, positive customer reviews, and responsive customer service are all indicators of a reliable supplier. At Coropak, we pride ourselves on our swift, 7-day turnaround times for container shipments and our round-the-clock production capabilities.
