40 × 30 × 20 cm Reference Size
A practical medium-large cooler format with a wide 20 cm rectangular bottom for food containers, drinks and picnic supplies.
Tapered Side Gussets
The side panels narrow toward the zippered top and expand toward the flat base, creating useful internal capacity without a bulky upper profile.
Dotted Non-Woven Exterior
Textured non-woven fabric gives the bag more structure and a more finished appearance than a basic smooth promotional tote.
Reflective Insulated Interior
The inner thermal lining helps slow temperature transfer for food, beverages and short-distance insulated carrying.
Box-X Reinforced Handles
Folded non-woven handles are secured with reinforced Box-X stitching at the attachment points.
A structured non-woven insulated cooler bag with tapered side gussets, a flat 20 cm bottom, reflective thermal lining and reinforced folded handles. Suitable for picnic, grocery, food and beverage promotions, retail programs and custom OEM cooler bag projects.
This non-woven insulated cooler bag uses a tapered gusseted construction rather than a simple flat tote shape.
The current reference version measures approximately 40 × 30 × 20 cm. Its side gussets narrow toward the zipper opening and expand toward a 20 cm wide flat rectangular bottom, creating useful space for meal containers, bottled drinks, packaged groceries and picnic supplies.
The wide base also makes rectangular food packaging easier to arrange inside the bag compared with narrow lunch bags or flat promotional coolers.
The bag has clearly defined triangular side gussets that create a wider base and a narrower upper profile.
Bound exterior seams run along the side structure, helping finish the exposed edges while giving the cooler bag a more defined three-dimensional shape.
This construction is suitable for carrying:
Meal containers
Bottled and canned drinks
Grocery products
Fruit and snacks
Picnic supplies
Promotional food sets
Takeaway items
For OEM projects, the base depth, height and opening dimensions can be adjusted around the actual products being packed.
The outer body uses dotted-texture non-woven fabric with a visible embossed surface.
The textured finish gives the bag more visual depth than plain non-woven material while keeping the overall construction lightweight and suitable for larger promotional or retail programs.
Non-woven fabric weight, color and surface specification can be selected according to the required appearance, carrying performance and project cost.
The reference bag uses a reflective silver thermal lining with an insulation layer.
This structure helps slow heat transfer between the contents and surrounding environment, making the bag suitable for chilled drinks, food containers, groceries and picnic use.
For custom projects, INITI can develop different insulation systems according to the intended application, including different foam thicknesses, reflective foil structures and PEVA lining options.
The handles are made from folded self-fabric non-woven material, matching the main bag rather than using standard woven webbing.
At the main attachment points, the handles use Box-X reinforced stitching. This reinforcement distributes stress across a larger sewn area and improves handle attachment durability during repeated carrying.
For projects requiring a different appearance or carrying specification, PP or polyester webbing handles can also be developed.
The top opening uses a nylon coil zipper with a metal slider and puller.
The zipper provides a more enclosed thermal compartment than an open-top insulated tote and gives users convenient access when loading food, drinks or grocery items.
Zipper color, puller shape and opening construction can also be customized for OEM orders.

The triangular side gussets expand toward the bottom, creating more usable internal volume without making the upper section unnecessarily wide.
The wide rectangular base provides practical support for lunch boxes, food trays, groceries and beverages.
The textured exterior gives the bag a more finished appearance and provides a useful surface for promotional branding.
The thermal lining helps reduce temperature exchange during short-distance food and beverage transport.
Folded non-woven handles are secured with reinforced box-and-cross stitching at the main stress points.
The nylon coil zipper helps keep the insulated compartment enclosed during carrying.
The broad front and back panels provide space for logos, promotional artwork and private-label branding.
