Secure by Design: PET Tamper Evidence Jars (4 oz – 32 oz)

Plascene’s PET Tamper Evidence Jars combine clear, lightweight PET with straight-sided geometry and a neck system designed to provide visible evidence of first opening. Available across compact and larger wide-mouth formats, the line gives brands a practical way to add package security without sacrificing product visibility, handling, or label space.

Manufactured in Oxford, California, the range can support products where package integrity matters from filling through final use, including specialty foods, wellness products, powders, creams, and other products that benefit from a clear indication that the package has remained unopened. With capacities from 4 oz to 32 oz, buyers can work within the same straight-jar language while matching the container more closely to the intended fill and use environment.

Built for visible security and practical packaging

• Tamper-evident neck design. The closure system can provide a visible indication of first opening, helping add another layer of confidence between filling, distribution, and final use.
• Straight-sided jar geometry. Clean walls provide generous label area and a familiar profile that is straightforward to handle, decorate, and integrate into established packaging programs.
• High-clarity, lightweight PET. PET keeps the contents visible while reducing the weight and breakage concerns associated with glass.
• rPET available. Every bottle in the line is designed to be fully recyclable, with recycled-content options available so brands can get ahead of California SB 54 and similar Extended Producer Responsibility rules before they become a scramble.

The value of the range is not limited to tamper evidence alone. The same straight-sided architecture also makes it easier to maintain consistent labeling and presentation as a product line moves between smaller and larger capacities, while the security feature remains part of the package rather than an afterthought.

The three distinct packaging profiles of Plascene’s PET Tamper Evidence Jars

4–8 oz — compact straight jars

The 4 oz and 8 oz formats form the most compact end of the line, with straight-sided proportions that keep the package small, clean, and easy to handle. These jars are well suited to lower-volume fills where visible tamper evidence is important but a larger wide-mouth footprint would be unnecessary.

Their compact geometry makes them a practical option for concentrated powders, capsules, creams, specialty ingredients, and other products that benefit from a secure, straightforward presentation in a smaller package.

12–20 oz — low-profile, wide-body jars

The 12 oz, 16 oz, and 20 oz formats have a noticeably wider silhouette that gives them a more substantial opening and an easy-access presentation. Their proportions work especially well for products that are scooped or applied directly from the jar, with the broad body providing a strong surface for branding and product information.

This makes the group particularly well suited to creams, body butters, balms, and other cosmetic or personal-care formulations where accessibility, shelf presence, and a premium wide-mouth appearance are important.

25–32 oz — taller, higher-volume jars

The 25 oz, 30 oz, and 32 oz references move into a broader, more substantial jar profile. The larger body gives these formats a stronger shelf presence and more internal volume while retaining the same 89mm tamper-evidence neck platform used by the 12–20 oz group.

This makes them a natural fit for higher-count gummies, larger powder fills, bulkier specialty foods, body-care products, and other applications where capacity and easy product access carry more weight than keeping the container visually compact.

The taller body also changes how the package presents itself. Compared with the 12–20 oz jars, these formats can feel more substantial and more suited to family-size, value-size, or repeat-use products, while still preserving the same straight-sided design language across the range.

Specifications at a glance

These applications are general packaging guidelines rather than fixed limitations. Final jar selection should reflect the actual product, fill volume, closure system, jar proportions, and production requirements. If you are comparing nearby capacities, request a sample to confirm fit with your product and packaging setup before final specification.

Which size should you consider for your product?

The right size depends less on a simple progression from small to large and more on how the jar’s proportions fit the product. Across this range, the three size groups create noticeably different packaging profiles, so capacity, access, shelf presence, and handling should all be considered together.

• Compact formats make sense when minimizing footprint, keeping the package easy to handle, and avoiding unnecessary headspace are the main priorities.
• Wide, low-profile formats are worth considering when direct access, a broader opening experience, and a lower shelf profile are more important than maximizing vertical label area.
• More substantial formats provide greater internal volume and a stronger physical presence, making them a better fit when capacity, repeat use, or a larger package format carries more weight in the specification.

The 12–20 oz and 25–32 oz groups share the same 89mm tamper-evidence neck platform, so the distinction between them comes primarily from capacity and body geometry rather than opening size. The lower, wider proportions of the 12–20 oz jars create a noticeably different presentation from the broader, higher-volume 25–32 oz formats, while the 4–8 oz group remains the most compact option in the range.

Ultimately, the most suitable reference depends on the customer’s target fill, desired package proportions, closure requirements, labeling needs, and existing filling or packing setup. Plascene provides the range of stock options; the final choice remains with the packaging specification already established for the product.

Need it customized? We build at wholesale scale

These stock references are ready-made starting points — but they aren’t your only options. For brands that want a distinct shelf presence, Plascene also produces custom work: custom colors and tints, tailored rPET content, specialty decoration, and fully custom shapes on a dedicated (private) mold.

Customization in PET packaging is a wholesale conversation, and the minimum order quantity (MOQ) scales with how far you take it:

• Stock references (like the ones above) are available in standard case and pallet quantities — the lowest commitment and the fastest path to market.
• Custom color, tint, rPET blend, or decoration typically starts in the tens of thousands of units per run (commonly around 10,000–50,000), because the line has to be set up, purged, and dedicated to your spec.
• A private (custom) mold — a unique jar shape only your brand can use — is the biggest step. Because tooling is amortized across the run, dedicated-mold programs generally make sense at higher volumes, often in the 50,000–100,000+ unit range.

These are industry-typical guideposts, not fixed rules — actual MOQ depends on the jar, the closure, the decoration, and your production schedule, and each can be confirmed at the quote stage.

A U.S. supply partner — not just a bottle vendor

Packaging decisions for pharmaceutical and supplement brands increasingly come down to more than unit price. With domestic production in Oxnard, California, Plascene offers competitive lead times, closer collaboration on custom projects, and a supply chain built to keep moving when demand tightens. For brands navigating SB 54 and the broader shift toward recycled content, that means a partner who can help plan material strategy through the company’s sustainability program — not just fill a purchase order.
