Why Sana Packaging Developed the 38-400 Ocean Screw-Top Lid

Originally published July 2021. Updated August 2026.

When Sana Packaging introduced the 38-400 Ocean Screw-Top Lid in 2021, the goal was to add a reclaimed-material closure to its cannabis packaging system.

Small glass jars were already a familiar format for cannabis concentrates, but the jar was only one part of the finished package. Brands also needed a compatible closure that could meet child-resistant packaging requirements while reducing virgin plastic use in the lid.

The result was a child-resistant push-and-turn closure made in the United States from 100% reclaimed, ocean-bound high-density polyethylene (HDPE).

The 38-400 Ocean Screw-Top Lid remains part of Sana Packaging’s current packaging lineup. This article explains why the lid was developed and the role it serves within a complete package. Current specifications, configurations, quantities, pricing, customization, and availability should be confirmed on the product page and in the applicable quote.

Address a Specific Closure Need

Cannabis concentrate packaging often combines a small glass jar with a separate lid.

The jar and lid perform different functions and may be made from different materials. Selecting a glass jar does not determine the material, opening action, child-resistant status, liner, or sealing characteristics of the closure.

The 38-400 Ocean Screw-Top Lid was developed to give brands another option for this part of the package.

Its 38-400, 6-TPI neck finish allows it to work with compatible containers using the same finish. The push-and-turn opening action provides the child-resistant mechanism documented for the closure.

The lid was not intended to make every jar or closure format unnecessary. Different products and markets may require different container sizes, neck finishes, liners, opening actions, tamper-evident components, or packaging formats.

Its purpose was more specific: provide a compatible child-resistant closure that incorporates reclaimed material into a commonly used jar-and-lid system.

Use Reclaimed Ocean-Bound HDPE in the Lid

The 38-400 Ocean Screw-Top Lid is made from 100% reclaimed ocean-bound HDPE.

Using reclaimed plastic as a manufacturing input can reduce the need for virgin plastic in the component to which the claim applies. In this case, the recycled-content claim applies to the lid body.

It should not automatically be extended to:

• The glass jar.
• The liner.
• A label or adhesive.
• A tamper-evident component.
• An insert.
• Paperboard packaging.
• Any other part of the finished package.

The lid body is made from #2 HDPE and is recyclable where accepted. Local collection and processing programs vary, and the liner, label, residual product, or other attached components may affect the available end-of-life pathway.

The use of reclaimed HDPE does not make the lid biodegradable or compostable. Recycled content, recyclability, biodegradability, and compostability are separate material characteristics.

The broader sourcing, documentation, and environmental context for ocean-bound plastic belongs in Sana Packaging’s dedicated material information. This product story is limited to why the material was incorporated into this particular closure.

Build Around a Familiar Neck Finish

A neck finish provides a starting point for determining whether a container and closure are dimensionally compatible.

The 38-400 Ocean Screw-Top Lid was designed for containers with a compatible 38-400, 6-TPI neck finish. Sana Packaging’s current product page identifies the containers intended to pair with the lid.

A matching neck-finish designation does not establish every aspect of finished-package performance. The complete configuration can also be affected by:

• The specific jar.
• The selected liner.
• Application torque.
• Filling and closing procedures.
• Product contact.
• Label or tamper-evident components.
• Storage and transportation conditions.
• Normal manufacturing tolerances.

For that reason, compatibility should be confirmed for the actual container, lid, liner, and product rather than inferred from the neck-finish designation alone.

Treat the Lid as Part of a Complete Package

The 38-400 Ocean Screw-Top Lid is a closure, not a complete package.

The finished configuration may include:

• A compatible jar.
• The 38-400 Ocean Screw-Top Lid.
• The selected liner.
• A label or printed decoration.
• A tamper-evident component when required.
• Any insert or outer packaging.
• Required product information and opening instructions.

Child resistance and tamper evidence remain separate characteristics. The child-resistant opening action does not automatically provide visible evidence that the package has been opened. A tamper-evident label, band, or seal does not, by itself, make the package child-resistant.

The documented child-resistant configuration, intended market, and complete package should be reviewed before commercial production. The actual product should also be tested with the selected jar, lid, liner, and production process.

Brands planning an entire concentrate packaging line can review "How to Build Custom Cannabis Concentrate Packaging." That guide addresses the broader relationship among jars, closures, liners, labels, tamper-evidence, paperboard displays, quantities, and production planning.

Keep Current Product Information on the Product Page

The original 2021 article announced the Ocean Screw-Top Lid as a new addition to Sana Packaging’s concentrate-packaging lineup.

Product configurations and commercial details can change after a launch announcement. Available colors, liners, case and pallet quantities, pricing, customization options, documentation, inventory, and lead times should therefore be sourced from the current product record rather than the original article.

The 38-400 Ocean Screw-Top Lid product page should be treated as the source of truth for current product information.

Product-specific FAQs provide additional answers about compatibility, child resistance, material, liners, sealing, customization, samples, and ordering. Those practical questions should be reviewed alongside the product page rather than relying on this product origin story as a technical specification or purchasing document.

Continue the 38-400 Ocean Lid Product Story

The 38-400 Ocean Screw-Top Lid expanded Sana Packaging’s product system by applying reclaimed ocean-bound HDPE to a child-resistant closure.

Its role is not to replace every lid, jar, liner, or concentrate-packaging format. It provides another option for brands evaluating material inputs, compatible containers, closure requirements, product fit, customization, and commercial production.

The appropriate package is the complete configuration that works with the actual product, production process, intended market, storage and transportation conditions, and customer use.
