Bullet shape metal detectable earplugs are CLW's affordable workhorse — designed for high-turnover food manufacturing environments where staff get a fresh pair daily and disposed at the end of every shift. Each plug contains a small metal core that triggers food-industry metal detectors if accidentally lost in product, providing the contamination protection HACCP-compliant facilities require. Comfortable foam, NRR ~33 dB, 100 pairs per box.
Why Metal-Detectable Matters
If a regular foam earplug ends up in product passing through your metal detector, it won't trigger — and that means contamination reaches consumers. The fix is metal-detectable earplugs containing a metal element that does trigger detection equipment. Lost earplug? Detector catches it before product ships. This is mandatory in HACCP-compliant facilities running metal-detection programs and is one of the most common audit findings when missing.
Bullet Shape Design
The tapered bullet profile makes insertion fast and consistent — even staff new to wearing earplugs can place them correctly without training. The foam expands to fill the ear canal, creating a comfortable seal without pressure points. The shape also makes them easier to handle with gloved hands, which matters in food production environments where staff are gloved-up all shift.
The Value Choice
This is our most affordable metal-detectable earplug — chosen by facilities that issue daily fresh plugs to large staff numbers. The math: a 30-person operation goes through 30 pairs per shift × 5 shifts = 150 pairs per week, or about 7,800 pairs per year. That's ~78 boxes annually. The savings vs premium-brand earplugs adds up to meaningful dollars over a year while delivering the same compliance and detection performance.
NRR ~33 dB Hearing Protection
The Noise Reduction Rating of approximately 33 decibels exceeds OSHA and Canadian hearing protection requirements for most food production environments. Packaging lines, mixing rooms, and cleaning zones typically run 85-95 dB sustained noise — bullet earplugs reduce that to safe levels for full-shift wear. For louder environments (e.g., heavy machinery rooms above 100 dB), pair with over-ear protection.
Frequently Asked Questions
Why bullet shape vs other earplug shapes?
The tapered bullet design is easier to insert correctly without training, expands consistently to fill the ear canal, and is easier to handle with gloved hands. For most food production environments, bullet shape is the practical choice.
Will any earplug work for food manufacturing?
No — only metal detectable earplugs. Regular foam earplugs don't trigger metal detectors, which means a lost earplug could end up in product and reach consumers. HACCP-compliant facilities require metal detectable earplugs, and inspectors look for them during audits.
How loud is too loud — when do staff need earplugs?
OSHA and Canadian standards require hearing protection above 85 dB sustained exposure. Most food production environments — packaging lines, mixing rooms, cleaning zones — exceed this threshold. The bullet earplugs provide ~33 dB NRR (Noise Reduction Rating).
What's the difference between Bullet Shape and Laser Trak Honeywell?
Bullet Shape and Laser Trak are both single-use metal-detectable foam earplugs. The difference is the cord and the brand. Laser Trak (Howard Leight by Honeywell, model LT-30) is corded — the plugs stay accessible to workers moving between noisy and quiet zones, and the cord prevents loss into product or equipment. Bullet Shape is uncorded — simpler, lower cost per pair, best for high-turnover daily-issue environments where the cord doesn't add value. Both have metal-detectable elements in the earplug body. Choose Laser Trak if you need the cord workflow or your procurement program requires Howard Leight branding; choose Bullet Shape for the most economical option.
Are these reusable or disposable?
Disposable single-use. The foam compresses and degrades after a shift, so reusing them defeats the seal. Plus, the per-pair cost is so low that fresh issue per shift is the practical standard.
Do all metal detectors detect these?
Standard food-industry metal detectors used in Canadian production lines reliably detect them. If your facility uses unusually low-sensitivity detection, contact us for a sample to test before placing a large order.
