IDL Packaging 14″ x 14″ x 14″ Insulated Shipping Box
The IDL Packaging 14″ x 14″ x 14″ insulated shipping box combines a sturdy cardboard outer shell with EcoMax Thermal-Paper insulation liners. The box offers a 5.8-gallon internal capacity and a 1.5-inch-thick liner that, when paired with ice packs, can help keep contents cold for up to 72 hours. Its liner is a multilayer construction with a kraft paper shell and internal cellulose wadding, designed to protect against moisture and microbial growth. Aimed at frozen food, meat, or fish shipments, these liners help absorb condensation and reduce spoilage risk while remaining paper-based.

CH-BOX offers a four-pack of insulated shipping boxes designed for perishable shipments. Inner dimensions around 14.375″ x 9.375″ x 10″ with an outer size near 15″ x 10″ x 11″ after sealing. The set uses aluminum foil foam liners to minimize heat transfer and provide reliable insulation for cold and cooled items. These boxes are well-suited for shipping perishable foods, frozen breast milk, meat, fish, or fruit, with an emphasis on leak resistance and consistent temperature maintenance.
meekoo 30 Pcs Insulated Box Liners
This bulk set from meekoo includes 30 insulated bag liners with a metallic exterior and a white interior, designed for convenient transport. Constructed from pearl cotton and aluminum foil, these liners offer waterproof, reusable, and cushioning properties to protect contents during transit. They provide about 0.12 inches (0.3 cm) of insulation thickness, supporting longer cold or hot retention when placed inside appropriate containers or boxes.
25 Pack Bubble Foil Insulated Box Liners
Elite Tool Center offers a 25-pack of 12″ x 12″ x 12″ bubble foil insulated liners with self-sealing capability. The bubble foil design provides an effective barrier against temperature fluctuations and light moisture while remaining easy to seal and transport. These liners are sized for compact shipments and are suitable for a range of perishable items requiring reliable cold or cool transport in a cost-effective format.
ROTCH Insulated Shipping Boxes With Liners (8 Pack)
ROTCH provides an eight-pack of small insulated shipping boxes with foil foam bag liners. Each box measures about 14.375″ x 9.375″ x 10″ inside, with an outer dimension of 15″ x 10″ x 11″ after sealing. At roughly 13.7 ounces per box, this set balances portability with insulation performance, making it suitable for small-to-medium perishable shipments such as frozen foods, meals, or temperature-sensitive medical supplies. Perishable markings and clear orientation arrows help with proper handling during transit.

These durable, waterproof, and reusable bags are suitable for shipping seafood, fruit, beverages, or hot foods, and can also serve as camping or picnic insulation solutions when needed.
Buying Guide
- Insulation material and thickness: A thicker liner (around 1.5 inches) typically provides longer cold retention, especially when used with ice packs. Look for multilayer constructions combining kraft paper, foil, and foam for moisture control and structural integrity.
- Box versus liner: Boxes with integrated liners can simplify packing and reduce leakage risk, while standalone liners offer flexibility to fit existing boxes or containers of specific sizes.
- Temperature range and retention: Consider the target storage window (e.g., 24–72 hours) and the type of product being shipped (frozen, chilled, or ambient but temperature-sensitive).
- Moisture and microbial protection: Paper-based and foil-laminate designs can reduce condensation and microbial growth better than basic plastic insulators in some scenarios.
- Pack size and scalability: Bulk liner sets are cost-effective for high-volume shipping; smaller packs may be better for occasional use or niche shipments.
- Environmental impact and reuse: Paper-based liners and reusable foil-insulated bags provide different sustainability profiles—consider disposal needs, recycling options, and reuse potential.
- Ease of use: Self-sealing options and pre-cut liners reduce prep time. Ensure compatibility with your standard shipping boxes and handling workflow.
- Regulatory alignment: For medical or food shipments, confirm compliance with relevant health and safety guidelines and documentation requirements.
