The 38mm White Hinge Gard Closure with IHS lining is a high-performance, tamper-evident closure solution engineered for manufacturers and brands packaging supplements, powders, and dry formulations across pharmaceutical, nutraceutical, food, and health care markets. Compatible with PET, HDPE, and glass containers — including the widely used Petpacker jar range — this closure offers broad applicability across container types without compromising on sealing integrity or user convenience.
Manufactured from white polypropylene (PP), the Hinge Gard Closure combines robust construction with a functional hinged design that sets it apart from standard screw-top closures. The integrated hinge allows the lid to remain attached to the cap body when open, eliminating the risk of misplaced lids and enabling controlled, one-handed dispensing — a practical feature for both consumer use and professional or clinical environments.
The IHS (Induction Heat Seal) lining is the defining functional element of this closure. During the sealing process, induction heat sealing technology bonds the liner to the rim of the container, creating an airtight, leak-proof barrier that provides tamper-evident assurance from the point of filling to the moment of first consumer use. The sealed liner must be punctured or removed before the product can be accessed, delivering clear, visible evidence of product integrity that is a critical requirement across supplement, pharmaceutical, and food packaging markets.
This combination of hinged convenience and induction heat seal security makes the White Hinge Gard Closure a compelling choice for products where both tamper evidence and ease of repeat access are essential. Whether applied to protein powders, vitamin supplements, herbal blends, or dry health food products, this closure delivers the performance, compliance, and presentation that modern retail and regulated markets demand.

Frequently Asked Questions (FAQs)
What containers is this closure compatible with?
This closure is designed for containers with a 38mm neck diameter, including PET, HDPE, and glass formats. It is specifically compatible with Petpacker jars.
What is an IHS liner and how does it work?
IHS stands for Induction Heat Seal. The liner is a foil-based material bonded to the underside of the closure. During the capping process, an induction sealing machine generates an electromagnetic field that heats the foil liner, bonding it directly to the rim of the container to form an airtight, hermetic seal. The result is a tamper-evident barrier that must be removed or pierced before the product can be accessed for the first time.
What are the benefits of induction heat sealing over standard liners?
Induction heat sealing creates a stronger, more consistent bond than pressure-sensitive or foam liners, delivering superior airtight and leak-proof performance. It also provides a higher standard of tamper evidence, as the foil seal cannot be reapplied once removed, making it clearly visible to consumers that a product is intact and uncompromised.
What is the hinged design and why is it beneficial?
The hinged closure features an integrated hinge connecting the lid to the cap body, meaning the lid remains attached when open rather than being fully removed. This prevents lids from being lost or contaminated during use, enables one-handed operation, and supports controlled dispensing.
Is this closure suitable for food and supplement products?
Yes. The White Hinge Gard Closure is well-suited for nutritional supplements, herbal powders, and similar formulations. As with all packaging, ensure the complete container and closure combination meets the specific regulatory requirements for your product category and target market.
Does this closure require specialist equipment to apply the IHS seal?
Yes. Activating the IHS liner requires an induction sealing machine, which generates the heat needed to bond the foil liner to the container rim. Induction sealers are widely used across pharmaceutical, nutraceutical, and food manufacturing environments and are available in a range of formats from handheld units to fully automated inline systems.
Is polypropylene a safe material for food and supplement packaging?
Yes. Polypropylene (PP) is a widely approved and trusted material for food contact and pharmaceutical packaging. It is lightweight, chemically resistant, and compliant with international food contact material regulations including EU and FDA standards.
Can I customise this closure with my brand?
Yes. BlueSky offers decoration and enhancement options from stock with a minimum order quantity of 2,500 units. For non-stock customisation, MOQs are subject to supplier terms. Please contact us to discuss your design requirements and we will advise on the most suitable customisation route for your brand.
Are these closures available in bulk?
Yes. These closures are available in bulk quantities suitable for manufacturers, contract packagers, and packaging distributors at all scales. Please refer to the product listing for available pack sizes and volume pricing, and contact us for high-volume enquiries.
Is polypropylene recyclable?
Yes. Polypropylene is a recyclable plastic, though collection and processing rates vary by region. Please refer to your local recycling guidelines for specific disposal instructions.
