38mm HDPE Tamper Evident Screw Caps - Case of 100
Frequently Bought Together
RELIABLE 38 MM TAMPER-EVIDENT CLOSURES
Engineered for HDPE blow-molded and PET injection-molded bottles that use a proprietary three-lead 38 mm neck finish, these screw caps deliver instant, irreversible tamper evidence. The patented "J" band separates cleanly on first opening, remaining on the bottle so customers can see the seal has been broken at a glance.
Molded from FDA-compliant black HDPE in the USA, each unlined cap applies with standard torque equipment and requires up to 50 % less top load than conventional closures—saving time and reducing stress on the container. Supplied in a convenient case of 100 units, they are ideal for dairy, juice, and other cold-fill, non-carbonated products.
APPLICATION NOTE
Not recommended for carbonated, hot-fill, nitrogen-injected, or frozen products. Always test your bottle-cap combination for leak integrity before full-scale production.
KEY ADVANTAGES
IDEAL APPLICATIONS
Dairy & Juice Bottling
Provides reliable, easy-to-see tamper evidence for fresh milk, flavored dairy drinks, smoothies, and cold-filled juices packaged in HDPE or PET bottles.
Still Beverage Production
Ideal for bottling non-carbonated water, teas, sports drinks, and cold-brew coffee where a secure seal and consumer confidence are critical.
Sauce & Condiment Lines
A great fit for cold-filled sauces, marinades, and dressings—maintains product integrity without the need for high top-load capping equipment.
Pharma & Nutraceutical Liquids
Ensures tamper-evident protection for syrups, vitamin shots, and diagnostic solutions packaged in compatible 38 mm neck-finish bottles.
HDPE CONSTRUCTION & DESIGN
These 38 mm tamper-evident screw caps are injection-molded from food-grade High-Density Polyethylene (HDPE), giving packagers a sturdy, lightweight closure that pairs seamlessly with compatible bottles. Key material and design advantages include:
- Patented "J" tamper band that provides unmistakable evidence of first opening
- Unlined HDPE interior—no liner to dislodge or contaminate product
- 3-lead thread for fast, secure engagement on proprietary neck finishes
- Requires roughly 50 % less top-load force during capping, reducing equipment strain
- Tamper band remains on the bottle after opening to simplify recycling and disposal
PERFORMANCE PARAMETERS
Patented "J" band breaks cleanly on first removal, leaving a residual ring for clear product-security verification.
Compatible with standard automated torque equipment; low-profile design cuts required top-load by approximately 50 %.
Engineered for 38 mm three-lead DBJ neck finishes on HDPE blow-molded and PET injection-molded bottles; not interchangeable with SSJ closures.
Not recommended for carbonated products, hot-fill applications, nitrogen-gas injection, or freezing conditions.
Compatible Bottle
Pair these tamper-evident caps with 4-32 oz. BPA-Free Food-Grade Square Bottles
PRODUCT FEATURES
Are the caps food-safe for dairy, juice, or water applications?
Yes. They are injection-molded from FDA-compliant HDPE and contain no added liners or coatings, making them suitable for direct food contact in dairy, juice, and other still-beverage markets.
Are these closures appropriate for carbonated, hot-fill, or nitrogen-dosed products?
No. The manufacturer does not recommend using this cap for carbonated beverages, hot-fill processing, nitrogen gas-injected packaging, or any product that will be frozen.
Does the tamper band stay on the bottle after opening?
Yes. The patented "J" tamper band separates from the closure skirt during the first removal and remains locked around the bottle neck, providing clear evidence of opening without creating loose plastic pieces.
How many caps are included in one case?
Each case contains 100 HDPE tamper-evident screw caps.
What type of equipment is needed to apply these caps?
The closures are typically applied with standard, commercially available capping machines or handheld torque drivers. Thanks to the design’s 50 % lower top-load requirement, they seat securely without excessive downward force.
Can I interchange DBJ caps with SSJ caps on the same bottle?
No. DBJ and SSJ closures use different thread profiles and tamper bands; therefore, they are not interchangeable. Always match the cap style to the specified bottle finish.
Do these caps include a sealing liner or gasket?
No. They are unlined, relying on the precision-molded HDPE sealing surface of both the cap and the bottle neck. Because bottle tolerances vary, in-house leak testing is strongly recommended before full-scale use.
