4.8mm Plastic Boning for Corsets, Lingerie & Dressmaking

Add lightweight structure and flexible support to your garments with our 4.8mm-wide plastic boning. Commonly used in corsets and lingerie, it helps garments retain their shape while allowing comfortable movement.

Its narrow width makes it ideal for fitted designs and smaller boning channels where a discreet finish is required. Suitable for corsets, bustiers, bras, bodices, bridalwear, eveningwear, costumes, swimwear and other structured garments.

Plastic boning can be cut to the required length, making it a practical choice for dressmaking and lingerie construction. For a comfortable finish, round or smooth the cut ends before inserting the boning into the channel.

Please note that plastic boning is best suited to garments requiring light or flexible support. For tight-lacing corsets or designs requiring stronger structural support, steel boning may be more suitable.

Frequently Asked Questions

What is plastic boning used for?
Plastic boning is used to add lightweight structure and support to corsets, lingerie, bras, bustiers, bodices, bridalwear, costumes, swimwear and other fitted garments.

Is this boning suitable for corsets?
Yes. It is suitable for fashion corsets, corset-style tops and garments requiring light or flexible support. Spiral or flat steel boning is generally more appropriate for tight-lacing and heavy-duty corsetry.

How wide is the boning?
The boning measures 6mm wide, making it suitable for narrow boning channels and designs requiring discreet support.

Can plastic boning be cut to size?
Yes. It can be cut to the required length. The cut ends should be rounded or smoothed before use to help prevent sharp corners from damaging the fabric or causing discomfort.

What size boning channel should I use?
Choose a channel slightly wider than 4.8mm so the boning can slide in without excessive movement. Always test the channel width with a small piece before constructing the finished garment.

What is the difference between plastic and steel boning?
Plastic boning is lightweight, flexible and suitable for garments requiring gentle support. Steel boning provides firmer, more durable support and is generally preferred for traditional or tight-lacing corsets.

Can I sew directly through the boning?
This depends on the particular construction of the boning. For best results, insert it into a suitable boning channel rather than sewing through it unless you have confirmed that it is designed to be sew-through.
