Product Features

Insulated Construction for Everyday Food Carrying

The insulated design helps reduce heat exchange between the inside of the bag and the surrounding environment. It can be used to carry packed lunches, snacks, drinks, and other food items during daily commutes, picnics, and short trips. Actual temperature retention depends on the contents, starting temperature, ambient conditions, and how frequently the bag is opened. For longer periods of temperature-sensitive food storage, suitable ice packs or other temperature-control measures may be necessary.

Durable Polyester Material

The outer material is polyester, selected for its practical combination of durability, lightweight handling, and suitability for customized bag production. The surface can accommodate branded graphics according to the selected printing method and artwork requirements. For businesses ordering bags in bulk, the material and construction can be reviewed during sample development before mass production.

Portable Design With Zipper Closure

A built-in carrying handle makes the bag convenient to transport between home, work, school, and outdoor destinations. The zipper closure helps keep the contents enclosed during normal carrying. The design is intended to balance portability and everyday functionality without adding unnecessary bulk.

Multiple Capacity Options

The listed capacity options are 15 L, 20 L, 24 L, and 30 L, providing choices for different carrying needs. Smaller formats may suit individual meals and snacks, while larger capacities can accommodate additional food containers and drinks. Buyers should confirm the final dimensions and internal configuration before ordering, particularly when the bag needs to fit specific lunch boxes or beverage containers.
