Frequently Asked Questions

What materials are used in your large cooler bags?

Our large cooler bags are crafted from high-quality, eco-friendly materials. The outer shell is typically made from recycled non-woven polypropylene (PP) or recycled PET fabric, which are both durable and water-resistant. The insulation layer is composed of thick, high-density foam that provides excellent thermal retention. The inner lining is a food-grade, leak-proof PEVA or aluminum foil material that is easy to clean and maintains temperature effectively. We ensure that all materials are GRS-certified, meaning they are sourced from verified recycled content and meet stringent environmental and social standards. This not only guarantees the sustainability of our products but also ensures they are safe for direct contact with food items. By choosing our large cooler bag, you are investing in a product that is both environmentally responsible and functionally superior.

How long does the large cooler bag maintain temperature?

The thermal performance of our large cooler bag is exceptional. Cold items, such as frozen goods, can be kept at safe temperatures for up to 12 hours, while hot dishes remain warm for up to 6 hours. This is achieved through a combination of thick insulation layers and a heat-sealed, reflective lining that minimizes heat transfer. The exact duration depends on external temperatures, the initial temperature of the contents, and the quantity of items packed. For best results, we recommend pre-chilling or pre-heating the bag with ice packs or hot water before loading. Our large cooler bag is designed to meet the needs of commercial use, such as catering deliveries and grocery distribution, where temperature control is critical. With this performance, you can confidently transport perishable goods over long distances without compromising quality.

Can I customize the large cooler bag with my logo?

Absolutely. We offer full customization services for large cooler bags, including printing your logo, brand name, or any desired design. We use advanced printing techniques such as rotogravure, screen printing, and heat transfer to produce crisp, vibrant, and long-lasting graphics. You can also choose from a variety of colors for the bag body, handles, and zippers. Our in-house design team can assist you in creating a prototype that perfectly reflects your brand identity. Whether you need a simple one-color logo or a complex multi-color design, we ensure high-resolution output that resists fading and peeling. Additionally, we provide free mockups and samples for approval before mass production. This customization not only enhances brand visibility but also adds a professional touch to your operations.

What are the available sizes and capacities?

Our large cooler bags come in a range of sizes to suit diverse needs. Standard capacities include 30L, 50L, 75L, and 100L, but we can custom-make bags in any size upon request. For instance, a 50L bag is perfect for wholesale grocery deliveries, while a 100L bag can accommodate large catering orders. The dimensions can be tailored to fit specific carrier boxes or storage spaces. We also offer variations in shape, such as rectangular, square, or tote styles, all designed for optimal space utilization and easy stacking. If you require a non-standard size, our factory can accommodate your specifications with minimal additional lead time. Please contact us with your desired dimensions, and we will provide a tailored solution.

How does the large cooler bag contribute to sustainability?

Our large cooler bags are a testament to our commitment to sustainability. They are made from recycled materials, reducing the demand for virgin plastics and decreasing landfill waste. The production process is designed to be energy-efficient, with water-based inks and eco-friendly adhesives. Moreover, the bags are durable and reusable, encouraging a shift away from single-use packaging. At the end of their life, the bags are fully recyclable, contributing to a circular economy.
