Flat-Mouthed Box with a Safety Latch — Secure Corrugated Packaging with Child-Resistant Closure

Qingdao Bejan Giant New Packaging Science & Technology Co., Ltd. is a professional manufacturer specializing in custom corrugated boxes for global brands. We provide factory-direct OEM and ODM services with flexible customization, premium printing, rigorous quality control, and reliable international export.

Manufactured from high-quality corrugated board with precision flute profiles and a flat-mouthed structural design with an integrated safety latch closure, our flat-mouthed boxes are widely used for pharmaceutical packaging, child-safe product packaging, food and supplement containers, cosmetic product boxes, e-commerce shipping, retail packaging, and household product packaging. Every box is engineered to provide a flush, flat lid surface with a secure latching mechanism that resists accidental opening — adding an extra layer of protection for sensitive or regulated products.

Whether you need a small batch of safety-latched corrugated boxes for product compliance or large-volume production of secure flat-mouthed packaging for retail distribution, our experienced team can help you create packaging that meets safety requirements without compromising presentation.

Why Choose Our Flat-Mouthed Boxes with Safety Latch

Flat-Mouthed Design — Flush, Clean Top Surface

Unlike boxes with raised or recessed lids, our flat-mouthed design features a perfectly flush top surface where the lid sits level with the box body.

Our design ensures:

• Flat, even top surface — no raised edges, no gaps

• Clean, uninterrupted surface for printing and branding

• Stack-friendly flat top for stable palletization

• Consistent appearance from every angle

• Sleek, rigid-box-inspired aesthetic in corrugated material

The result is packaging that looks like a premium rigid box but delivers the cost and weight advantages of corrugated board.

Integrated Safety Latch Closure

The safety latch mechanism provides a secure, intentional closure that resists accidental opening during handling and transit.

Our safety latch ensures:

• Positive latching — latch engages with an audible or tactile click

• Resists accidental opening from impact or jostling

• Child-resistant option available for regulated products

• Tamper-evident option with adhesive strip complement

• Easy intentional opening for the end user

• Consistent latch engagement across all production units

The result is a box that stays closed until you want it open — with an extra layer of security for sensitive contents.

Flush Lid — No Tabs, No Overhang

The flat-mouthed design means the lid sits flush with the surrounding structure — no protruding tabs, no overhanging edges.

Our construction ensures:

• Clean silhouette with no protruding components

• Smooth edges on all sides — no snagging on other boxes

• Professional presentation suitable for retail display

• Compatible with overwrap and shrink-wrap packaging lines

• Consistent fit between lid and body

The result is packaging that presents a clean, unbroken surface — ideal for printed retail boxes and gift packaging.

One-Piece Construction — Ships Flat and Assembles Fast

The entire box, including the flat-mouthed structure and safety latch, is die-cut from a single piece of corrugated board.

Our construction ensures:

• Single-piece design — no separate lid or body components

• Ships flat — minimal storage space, reduced freight cost

• Quick assembly — fold and load in seconds

• No gluing or taping required for assembly

• Consistent structural integrity

The result is efficient logistics from factory to fulfillment center to end user.

Available in Multiple Flute Profiles

Select the right corrugated flute for your product weight and closure strength requirements.

Our material selection ensures:

• A-Flute for maximum cushioning and structural rigidity

• B-Flute for balanced strength and print surface quality

• C-Flute for general shipping and medium-weight products

• E-Flute for lightweight products requiring premium print appearance

• F-Flute for small, lightweight retail packaging

The result is a box with the right structural properties for both protection and latch performance.

Full-Color Offset Printing

The flat top surface offers an uninterrupted canvas for branding and product information.

Our printing ensures:

• CMYK full-color offset printing for vivid graphics

• Pantone color matching for exact brand reproduction

• Inside printing available for unboxing messaging

• Full-coverage printing on all exterior surfaces

• High-resolution image reproduction on the flush lid surface

The result is a box that uses every surface for brand communication — including the clean, flat top panel.

Premium Surface Finishing

Protect your graphics and enhance the tactile experience with professional finishing.

Our finishing ensures:

• Matte Lamination for elegant, non-reflective protection

• Gloss Lamination for bright, durable surfaces

• Soft Touch Coating for premium velvety feel

• Gloss UV for high-shine accent areas

• AQ Coating for scuff resistance

The result is packaging that feels as premium as it looks — and protects its appearance through the supply chain.

Tamper-Evident Option

Add an adhesive strip to provide visual evidence of first opening.

Our tamper-evident option ensures:

• Clear evidence if the box has been opened

• Peel-and-seal adhesive strip across the latch

• Complements the safety latch for double security

• Clean removal without damaging the box surface

The result is packaging that communicates security from the moment it arrives.
