Custom Flat Sliding Mint Tin Box for Pocket Candy Packaging

A Slim Metal Package Designed for Pockets

A conventional mint box may provide useful storage but still feel bulky when carried every day. The flat sliding mint tin focuses on a different requirement: keeping the package thin, easy to open and convenient to carry.

The shallow body reduces unnecessary height, while the rectangular outline fits naturally into pockets, small bags, travel pouches and promotional gift sets. For products that are used repeatedly throughout the day, the sliding action also creates a simple one-handed opening experience.

This format is particularly suitable for:

Breath mints, peppermint tablets, sugar-free candy, small hard sweets, fruit drops, compressed confectionery and individually wrapped mini candy.

How the Sliding Lid Structure Works

The lid sits over the upper edges of the tin body and travels horizontally along formed guide rails. One end of the lid remains open and flat, without the folded-down closing wall found on a conventional removable lid.

This open-ended construction is essential because it allows the cover to pass smoothly over the body during opening and closing.

A correctly developed slide tin should provide:

Smooth movement, controlled resistance, stable alignment and sufficient retention to reduce accidental separation during normal handling.

The sliding fit must be balanced carefully. A lid that is too loose may move during transport, while an excessively tight lid can scratch the body or become inconvenient for customers.

Sliding Lid Compared with Other Mint Tin Closures

Suitable Products for a Flat Slide Tin

Breath Mints

Small round or oval breath mints are one of the most suitable products for a sliding mint tin. The shallow structure makes individual pieces easy to reach without requiring a deep container.

Compressed Candy Tablets

Flat compressed sweets can be arranged loosely or packed inside a sealed pouch. Product thickness should be checked carefully to ensure sufficient clearance below the lid.

Fruit Drops and Hard Candy

Small fruit-flavoured drops, lemon sweets and other hard confectionery can use this format when their dimensions are compatible with the internal height.

Sugar-Free Sweets

A clean white, silver, blue or green package can support sugar-free mints and functional confectionery positioning.

Lozenges

Non-medicated herbal or throat sweets can be packed in a slide tin, provided that the required barrier, labelling and market regulations have been evaluated separately.

Mini Wrapped Candy

Individually wrapped sweets may also fit inside, although the wrapper folds require more volume than loose mint tablets.

The Open Lid End Must Remain Flat

The opening end is one of the most important structural details of a slide lid tin.

A traditional metal lid usually has folded walls on all four sides. That structure would prevent horizontal movement. On a true sliding tin, one short end remains open, allowing the lid to enter and leave the body rails without obstruction.

This edge should be:

Flat, smooth, accurately formed and free from unnecessary downward folding.

The opposite end may include a retaining structure that helps prevent the lid from sliding completely off during ordinary use, depending on the selected mould.

Finger Notch for Easier Opening

A small thumb notch can be formed in the body or along the lid-access edge to make the tin easier to open.

The notch should be large enough to provide grip but not so deep that it weakens the body edge or dominates the front appearance.

Its position also affects the artwork. Logos, text and decorative borders should not be placed directly over the formed notch area.

Controlling Sliding Resistance

The opening feel of a slide tin comes from the relationship between the lid, body rails and forming tolerance.

A premium result should not feel loose, unstable or excessively stiff. During sample approval, buyers should check:

The force required to begin opening, the smoothness of the movement, the alignment of both sides and whether the lid remains in position when the package is carried.

Printed coatings also influence friction. A glossy finish, matte varnish and unprinted metal edge may each produce a slightly different sliding feel.

Plan the Internal Height Carefully

A flat mint tin offers portability by limiting depth, but this also means that product height must be tested carefully.

If the mints sit too close to the lid, they may interfere with sliding. If excessive empty space is added, the package loses part of its pocket-friendly advantage.

The capacity should therefore be confirmed using:

The mint diameter, tablet thickness, target piece count, product arrangement and required headspace.

Physical filling tests using the actual confectionery are more reliable than estimating capacity from volume alone.

Loose-Fill Mints or Sealed Inner Packaging

Loose-Fill Format

Loose tablets create a simple opening experience and allow consumers to remove one mint at a time. The internal coating, cleanliness and food-contact requirements should be confirmed for the complete project.

Sealed Inner Bag

A flexible pouch can provide the main moisture and aroma barrier. The metal tin then supplies structural protection, branding space and reusable value.

Paper Liner

A paper liner can improve presentation and reduce direct contact between the confectionery and the interior surface.

Individual Wrapping

Small wrapped sweets can be used when the internal dimensions allow enough space for folded wrapper ends.

Freshness and Sealing Limitations

A standard sliding mint tin should not automatically be described as fully airtight.

The rails and open-ended lid construction are designed primarily for smooth movement rather than hermetic sealing. Small clearances may remain between the lid and body.

Products that are sensitive to moisture, aroma loss or long storage periods should normally use:

A sealed inner pouch, individual wrapper, protective film or another tested primary barrier.

The exact packaging system should be selected according to the confectionery recipe, expected shelf life and destination market.

Printing Across the Flat Sliding Lid

The broad, uninterrupted lid surface provides a useful canvas for brand presentation.

Common artwork layouts include:

A central logo, botanical mint illustration, flavour name, sugar-free message and small net-weight information.

The design should also account for the opening direction. Directional graphics and text should remain visually correct when the tin is displayed horizontally on a retail shelf.

Custom Finish Options

Fresh Botanical Artwork

Mint leaves, watercolour backgrounds and clean green tones suit peppermint, spearmint and herbal confectionery.

Minimal Private-Label Design

A plain background with a centred logo can create a modern and professional retail appearance.

Metallic Surface Effects

Silver, gold or exposed-metal details can add contrast without increasing the package thickness.

Embossed Branding

Selected logos or mint-leaf graphics can be raised, provided the embossing depth does not interfere with the sliding structure.

Matte or Glossy Varnish

Matte varnish supports a clean natural image, while glossy coatings enhance brighter candy colours.

A Practical Package for Travel and Everyday Carry

The thin profile allows the tin to fit into small spaces where a deeper box would be inconvenient.

Typical applications include:

Travel mint packaging, handbag candy tins, hotel welcome amenities, restaurant after-dinner mints, office giveaways and event promotional sweets.

The metal body protects the contents from crushing more effectively than a simple paper sleeve or flexible pouch.

Promotional Pocket Mint Tins

Flat sliding tins can be printed with corporate logos, campaign messages and event artwork for promotional use.

The lid remains attached through the sliding rails during ordinary opening, reducing the risk of customers misplacing a separate removable cover.

Suitable promotional projects include:

Trade shows, hotels, airlines, restaurants, conferences, automotive brands, healthcare campaigns and employee gift programmes.

Retail Display Opportunities

The flat rectangular shape allows the tins to be stacked, arranged in rows or packed into countertop display cartons.

Several flavour variants can share the same structure while using different colour systems:

Green for peppermint, blue for cool mint, light green for spearmint, yellow for lemon mint and red for berry-flavoured sweets.

A coordinated collection improves shelf recognition while reducing the need for separate moulds.

Private-Label Sliding Mint Tin Programmes

Mint producers, confectionery distributors and retailers can apply their own branding to the lid, body and underside.

One existing slide tin mould may support several SKUs, subject to the printing quantity required for each artwork.

The packaging can be developed for:

Breath mints, sugar-free tablets, fruit candy, herbal sweets, coffee candy and small promotional confectionery.

Difference Between Gum Tin and Gummy Tin

A gum tin usually refers to packaging for chewing gum pellets or gum pieces. A gummy tin refers to soft gummy candy.

Both products may fit inside a sliding metal box, but their packaging requirements differ.

Chewing gum pellets are generally firm and dry, while gummy confectionery may be sticky and moisture-sensitive. Gummies commonly require a sealed inner pouch rather than loose filling inside the tin.

Not a Hinged Tin

This product uses a horizontal slide lid and does not contain an external hinge.

A hinge rotates the lid upward around a fixed connection. A sliding lid instead travels along the length of the tin body.

Keeping these structures separate is important for product photography, tooling selection, cost calculation and customer expectations.

Existing Moulds and Custom Sizes

Jinyu maintains an extensive mould library covering slide tins, hinged tins, slip-lid tins and other metal packaging structures.

Using an existing flat sliding tin mould can reduce tooling investment and shorten the development period.

New tooling can be evaluated when the project requires:

A proprietary length, width, depth, thumb-notch position, rail profile or opening direction.

Development Process

1. Confirm the Confectionery

Provide the mint dimensions, tablet thickness, target piece count and inner packaging method.

2. Compare Available Slide Tin Moulds

Select a suitable flat rectangular structure according to capacity and portability.

3. Approve the Opening Direction

Confirm which end remains open and the direction in which the lid should slide.

4. Prepare the Artwork

Position the logo, flavour name and decorative graphics around the notch and forming areas.

5. Test a Physical Sample

Check the lid movement, retention, internal clearance, printing and customer opening experience.

6. Complete Mass Production

The tinplate is printed, coated, cut, stamped and formed according to the approved specification.

7. Inspect and Pack

Finished tins are checked and packed with suitable surface protection for export transportation.

Quality Control for Sliding Tin Boxes

Inspection can cover dimensions, rail alignment, opening resistance, lid retention, open-end flatness, thumb-notch position, printing registration and surface condition.

The lid should slide without abnormal scraping, twisting or becoming trapped along one side.

Because the structure contains moving metal surfaces, production consistency is especially important. Small forming differences can affect the final opening feel.

Frequently Asked Questions

Does the lid have a folded wall on all four sides?

No. One short end of a true sliding lid remains flat and open so that it can move smoothly along the body rails.

Is this a hinged mint tin?

No. The lid moves horizontally and does not use a hinge connection.

Can the sliding direction be customised?

The direction depends on the mould and artwork orientation. A new structure can be evaluated when a special opening direction is required.

Can the tin hold loose breath mints?

Yes, subject to the approved internal specification, food-contact requirements and required shelf-life protection.

Can gummies be packed inside?

Yes, but soft gummy candy normally requires a suitable sealed inner bag because the sliding tin itself is not a complete moisture barrier.

Is the sliding mint tin airtight?

No automatic airtight claim should be made for a standard slide lid. A sealed pouch or individual wrapping is recommended where stronger freshness protection is needed.

Can the lid be embossed?

Yes. Selected branding elements can be embossed if the location and depth do not interfere with the slide rails or lid movement.

Can a thumb notch be added?

Yes. A finger-access notch can be included according to the selected mould and required opening experience.

What is the standard MOQ?

The standard MOQ normally starts from 5,000 pieces per size or artwork. Final requirements depend on the mould, printing process and accessories.

How long does sampling and production take?

Sampling normally takes approximately 7–10 working days after the specifications are confirmed. Mass production generally requires approximately 25–35 working days after sample approval.
