Choosing cooler bags may seem easy, but the wrong choices in materials, insulation, or printing can affect both function and brand image.
Custom cooler bags are fully customizable insulated bags that help keep items cold or warm while promoting your brand. They offer flexible materials, printing methods, insulation options, and accessory choices to meet different business needs, from food delivery to corporate gifts.
While many clients initially think cooler bags are simple products, we know that real customization involves much more. In the following sections, I’ll walk you through the key factors — from structure design and materials to insulation layers, printing methods, and accessories — so you can clearly understand what matters when customizing your cooler bags.
Soft cooler bags, also known as soft insulated bags or thermal cooler totes, are lightweight and foldable, making them highly adaptable for a wide range of business purposes. Compared to hard coolers, soft designs offer greater flexibility in materials, shapes, and customization options.
Key Features:
Hard cooler bags, also known as hard-sided coolers or box coolers, are designed with a rigid plastic shell and high-density PU insulation. They are ideal for situations that demand long-lasting cooling and structural strength — such as outdoor camping, cold chain transport, and extended food delivery.
Key Features:
Fully Rigid Structure: Made with materials like HDPE or PP, these coolers are typically formed using injection molding or rotational molding processes. The entire body is rigid and impact-resistant, offering unmatched protection and stability.
Excellent Insulation Performance: Hard cooler bags usually contain thick polyurethane (PU) foam injected between the inner and outer walls. This structure can keep ice frozen for several days, making them perfect for camping, fishing trips, or professional cold-chain use.
Long-Term Durability: Designed to withstand heavy use, hard-sided coolers resist impact, UV rays, and rough outdoor conditions. Many models come with reinforced corners, gasket seals, and heavy-duty latches to prevent temperature loss.
Limited Branding Options: Compared to soft cooler bags, hard coolers usually offer limited space and surface compatibility for custom printing. However, some models allow for logo engraving or sticker branding, mainly for wholesale or retail channels.
Ideal Applications: Outdoor camping, fishing trips, road trips, medical cold storage, long-distance food delivery, cold chain logistics, and any setting where extended insulation is essential.
When you customize cooler bags, the outer material plays a big role. It shapes the overall appearance, reflects your brand image, and affects how durable and practical the bag will be for different uses. Here are the most common materials used for cooler bags, each offering its own unique advantages:
Nonwoven fabric is lightweight, affordable, and widely used for large promotional orders. With low minimum quantities, it’s perfect for short-term events or budget-friendly marketing projects. It’s easy to produce, supports a variety of printing options, and allows flexible design features. While it’s not as strong as woven fabrics, its cost-effectiveness makes it one of the most popular choices for corporate giveaways.
Oxford and polyester fabrics are strong, durable, and have a solid structure. They’re great for cooler bags that will be used frequently or carry heavier loads. The material holds its shape well and offers a more professional look, which is perfect for business gifts, outdoor activities, or company events. For brands that want both durability and a premium feel, Oxford is a top choice.
Cotton is a natural, eco-friendly fabric with good breathability. It helps reduce odors from repeated use and creates a soft, natural look. Brands that focus on sustainability often prefer cotton for its environmental benefits. Cotton cooler bags are popular for cultural events, non-profit organizations, and campus activities, where both practicality and brand image matter.
Laminated materials have a waterproof coating that makes them easy to clean and perfect for printing bright, eye-catching designs. Whether glossy or matte, they help brands create strong visual impact. These bags are often used for food delivery, short-distance transport, or large-scale promotions. For export orders, laminated bags made with ultrasonic sealing are thin, lightweight, and cost-effective for shipping.
Tyvek stands out with its light weight, flexibility, and unique paper-like texture. The original Tyvek material is soft and feels like fabric. After being laminated with nonwoven fabric, it becomes firmer and takes on a leather-like feel, ideal for high-end custom designs. Tyvek bags are durable, tear-resistant, water-repellent, and offer a clean surface for printing, making them popular with fashion brands, creative industries, and eco-friendly businesses.
Washable kraft paper has a natural, vintage look that feels a bit like real paper. Each bag has its own slightly different texture, giving it a handmade, unique appearance. The simple and retro style is perfect for creative brands, lifestyle products, and environmentally conscious designs. It helps brands stand out while adding a touch of quality.

Choosing the right printing method is key to making your custom cooler bags stand out with clear, vibrant designs and strong durability. Based on your artwork, bag materials, and order quantity, we offer several printing options:
Ideal for simple logos with solid colors or basic shapes. Produces vivid colors with sharp edges. Suitable for most materials including nonwoven, cotton, laminated, or oxford fabrics.
Best for multicolor, gradient, complex designs, or photo-style images such as real people or pets. Delivers detailed, realistic results with wide material compatibility. Applicable for nonwoven cooler bags, cotton cooler bags, oxford cooler bags, Tyvek cooler bags, polyester, and other soft insulated bags.
Mainly used for full polyester fabrics. Delivers bright, rich colors that fully penetrate the fibers, resulting in excellent color fastness and long-lasting prints. Perfect for colorful designs, cartoons, illustrations, and flat graphic styles. Less effective for photo-realistic images that require high depth or dimension.
Suitable for complex multi-color designs, including logos, icons, or illustrations. Works on many cooler bag materials with flat surfaces. Color vibrancy is generally lower than heat transfer or sublimation, and it has limited performance on highly realistic photo prints.
Primarily used for laminated materials in large-volume production. Provides precise color reproduction and smooth gradient transitions. Ideal for full-surface designs, photo-level detail, and high-end promotional cooler bags with large order quantities.
We will recommend the most suitable printing method based on your design files, bag materials, and order size. Before production, digital mockups or samples will be provided to ensure the final result meets your expectations.
Besides the outer materials and printing methods, the internal insulation structure directly affects cooling performance, product durability, and ease of cleaning. Depending on usage needs, we offer multiple insulation structure options for custom cooler bags:
This is the most widely used standard insulation structure. EPE (Expanded Polyethylene) foam provides effective insulation and cushioning. The aluminum foil is laminated directly to the foam during production, forming a ready-to-use inner layer.
PE foam serves as an independent middle insulation layer, offering solid insulation and structural support. The exterior can be paired with different linings based on functional needs:
Offers excellent reflective insulation and easy-to-clean surfaces. Available in smooth, snowflake, or embossed finishes depending on thickness and application.
Non-toxic, eco-friendly, soft, and durable. Safe for direct food contact, widely used in insulated lunch bags, reusable food cooler bags, and daily refrigerated lunch totes.
Highly waterproof, oil-resistant, and abrasion-resistant. Often used in specialized industries or custom insulated bags requiring stronger internal protection.
We offer a variety of functional accessories that can be freely combined according to your needs:
