Insulated Bag with Shoulder Strap

This insulated bag with shoulder strap features a three-layer structure designed for convenient carrying and temperature protection. The outer layer is made from polyester or oxford cloth in 210D or 420D options. The middle layer uses EPE foam with a thickness of 6 to 10 millimeters, while the inner layer is made from aluminum foil for improved insulation performance. Common sizes include 28×20×25cm and 32×24×28cm. The bag includes short top handles and an adjustable detachable shoulder strap with a length of 80 to 130 centimeters. The closure uses a zipper system for easy opening and closing. This insulated bag with shoulder strap can maintain temperature for 5 to 8 hours and carry 5 to 12 kilograms. A front external zippered pocket is added for storing utensils, phones, keys, and other small items.

The key feature of this product is the adjustable shoulder strap. The hands-free carrying design allows users to carry the bag comfortably while walking, cycling, or using public transportation. The strap length can be adjusted according to different body sizes, helping users achieve a more comfortable fit. The detachable design also provides flexibility. When the shoulder strap is not needed, it can be removed and the bag can be used as a standard hand-carry insulated bag. The external front pocket adds extra convenience because small items can be stored separately without opening the main compartment.

Strap Installation and Quality Focus

Our sewing workshop applies strict quality control to the strap installation process. The connection points must withstand repeated loading and pulling forces during daily use. We use multiple rows of stitching and back-stitching reinforcement at these areas to improve durability. The adjustable buckle is made from durable plastic material and is tested for smooth adjustment performance.

The external zippered pocket also requires precise sewing control. The pocket depth must provide enough space for phones and accessories while keeping items easy to reach. Before production completion, our workers check pocket dimensions and stitching quality to ensure consistent performance. We also conduct additional inspections on the shoulder strap, buckle strength, and connection points before shipment.

This insulated bag with shoulder strap is suitable for office workers carrying lunch, picnic activities, student meals, outdoor fishing, and daily commuting. The shoulder carry design improves comfort during extended use by distributing carrying weight across the shoulder. We support custom samples and logo printing services. Customers can choose different outer materials, colors, and customized designs. The minimum order quantity is 500 pieces. Free samples can be prepared to confirm strap comfort and product structure before bulk production. Mass production takes about 20 days.
