U-Type Air Column Bag

Custom U-Type Air Column Bags from KENT are supplied flat and inflated at the packing stage. Choose standard, special bottle or handle configurations, with dimensions and film thickness reviewed for your product and carton. Combine cushioning with compact storage before use.

At a Glance

• Supplied uninflated: Store compactly and inflate when needed.

• Multiple configurations: Review standard, bottle-fit and handle designs.

• Sized around your product: Flat dimensions differ from usable internal space after inflation.

• Part of a complete pack: Use suitable outer packaging for shipping.

How U-Type Air Column Bags Protect Your Product

U-Type Air Column Bags combine a pre-formed bag with inflatable columns to create cushioning between your product and its outer packaging. The bag provides a defined loading space for a repeatable packing arrangement.

A suitable fit means more than getting the product inside. The cushioning should cover the required areas and work with the outer carton.

Position Cushioning Around Your Product

For bottles, review the body, shoulders, neck and base. For other suitable items, check edges, projecting components and contact points.

Coverage depends on the selected configuration. Exposed areas may need additional cushioning or support within the outer packaging.

Keep Suitable Loading Clearance

The opening should allow insertion without forcing the bag apart. After inflation, the internal space should not leave excessive room for product movement.

Confirm dimensions using your actual product and an inflated sample, rather than flat measurements alone.

Key Features

Product-Fit Cushioning Layout

Position cushioning around your product’s shape to reduce direct contact with the outer carton.

Convenient Packing-Station Supply

Keep uninflated bags ready at the workstation and create cushioning space when packing begins.

Adjustable Dimensions and Film Specifications

Review dimensions and thickness around your product size, weight and outer carton requirements.

Options for Different Handling Needs

Select standard or special configurations according to your loading, coverage and carrying requirements.

Choose Your U-Type Air Column Bag

Standard U-Type Air Column Bags

Start with a standard configuration to assess loading and product coverage. Adjust the bag width, length and usable space around your item, then check the fit within a suitable carton.

Where the standard structure meets your requirements, focus on dimensions and film specifications without adding unnecessary packaging complexity.

Special Bottle-Cushioning Designs

Bottle shoulders, necks and bases can affect how well a standard bag fits. Special layouts with different cushioning zones can be assessed where a regular configuration does not match the bottle shape.

The aim is to position cushioning around the actual product—not to select a bag by bottle capacity alone.

U-Type Air Column Bags with Handles

Handle versions add a carrying position for packaging applications that require it.

Review the handle against the packed weight, grip space and intended use. Carrying convenience and shipping protection are separate requirements; a handle does not replace a suitable shipping carton.

U-Type Air Column Bag Specifications

Measurement note: Flat external dimensions are not the same as usable internal space after inflation. Define the measurement state, thickness basis and reference sample in the order.

Custom Fit for Your Product and Carton

Start with Actual Product Dimensions

Provide photographs, dimensions and weight of the product as it will be shipped. If retail packaging remains around it, measure the packed item.

For bottles, include height, maximum body diameter, shoulder and closure dimensions. Capacity alone—such as “750 ml”—does not determine the correct bag size.

Test the Bag and Carton Together

A sample assessment should cover both product insertion and the fit of the complete pack inside its carton.

Avoid excessive movement or a carton that compresses the columns when closed. Where needed, review bag dimensions, carton size and additional cushioning together.

Choose According to Coverage Requirements

A size mismatch may only require a dimension change. Different opening, top-coverage or carrying requirements may call for a different configuration.

Explore the wider Air Column Bag range, or compare Q-Type Air Column Bags and L-Type Air Column Bags for other coverage options.

Packing Tip: Test the Fit Before Bulk Ordering

Check the usable space after inflation, not only the flat bag dimensions.

Run a packing trial with your actual product and intended carton. Check loading clearance, excessive column compression and product movement after the carton is closed. Use the agreed sample and written specification as the basis for your bulk order.

Store Flat and Inflate When Needed

U-Type Air Column Bags remain compact before use. Compared with storing and transporting the same bags already inflated, flat supply reduces their volume before the packing stage and helps with stock storage and workstation planning.

This advantage relates to incoming packaging transport and storage. Freight for your finished product still depends on the final parcel dimensions, weight and carrier charges.

Applications for U-Type Air Column Bags

Wine and Other Suitable Bottled Products

Select a bag or special cushioning layout around the bottle shape. Check coverage at the body, shoulders and base, including whether the closure needs additional protection.

The bag provides cushioning. Bottle sealing and leak containment require their own appropriate measures.

Cushioning Inserts for Gift Boxes and Shipping Cartons

A suitably fitted U-type bag can serve as a cushioning component inside a gift box or shipping carton, separating the product from the box walls.

For multiple items in one carton, also review product-to-product separation rather than relying only on cushioning around the outside.

Custom-Fit Packaging for Other Products

If your product suits bag-style cushioning, send its dimensions, photographs and weight for a configuration review.

Sharp edges, projecting components and heavier loads require a separate assessment of contact points and the complete pack. Do not apply a bottle specification without checking suitability.

Inflation and Packing

Select a Compatible Inflation Method

Choose an inflation tool around the bag configuration and your daily packing volume. The inlet, tool compatibility and operating settings must suit the selected product.

Follow the instructions for that version when deciding whether to insert the product before or after inflation. Complete a sample packing trial before starting routine use.

Check the Finished Pack

Inspect the columns, product position, and support at the top and base before placing the pack in its carton.

Close the carton without forcing it against the columns. Check carrying performance separately for handle versions, and validate the complete pack against your shipping conditions.

Develop Your Custom Packaging Specification with KENT

Start with Your Packaging Problem

Tell KENT what you want to improve: product movement, a poor bottle fit, difficult loading or excessive packaging storage space.

Provide photographs, dimensions, weight and carton details so we can discuss the configuration and sample specification to assess.

Turn Sample Results into Order Specifications

After sample approval, record the design, key dimensions, film specification and packing quantity in the order. Special versions should also identify cushioning zones or handle positions.

This gives your bulk purchase a clear reference beyond a product name or photograph.

Keep Consistent References for Repeat Orders

Retain the approved sample and specification for repeat purchases and incoming checks. Review column layout, opening position, seals and key dimensions.

If the product, carton or handling method changes, reassess the fit before placing a repeat order.

Frequently Asked Questions

How Do I Choose Between Standard and Special Designs?

Start by checking whether a standard configuration meets your loading and coverage needs. Assess a special design if the shoulders, neck, base or carrying requirements do not fit suitably.

Will One Size Fit Every 750 ml Bottle?

Not necessarily. Bottles with the same capacity may differ in height, diameter and shoulder shape. Select the bag using actual bottle dimensions and packed weight.

How Do Flat Dimensions Differ from Inflated Dimensions?

Flat dimensions describe the outside of the uninflated bag. The columns occupy space after inflation, so the usable internal dimensions are different. Confirm suitability with an inflated sample and your actual product.

Can I Customize Film Thickness?

Yes. The usual thickness is approximately 60 μm, and other thicknesses can be discussed. Define the measurement basis and agreed specification in your order.

How Much Weight Can the Handle Version Carry?

Capacity depends on the construction, material and handling method. Provide the actual packed weight and validate the selected sample for its intended use.

Can the Bag Be Used as an Outer Shipping Package?

Do not assume it can be used as a stand-alone parcel package. Select suitable outer packaging for the product and shipping conditions. A handle does not replace validation of the shipping pack.

What Information Is Needed for a Quote?

Send product photographs, dimensions, weight, preferred configuration, expected quantity and carton details. Include an existing packaging sample if available.
