Membrane Box 75 x 75 x 25 mm

Description

Membrane Box 75 x 75 x 25 mm

Membrane-supported component protection

Product Overview

This membrane box is made with upper and lower high-clarity PS shells and transparent high-elastic membrane films. The outer size is 75 x 75 x 25 mm, and the usable inner size is 52.5 x 52.5 x 21 mm, making it suitable for compact components that need protected suspended positioning inside a clear package.

It is designed for fragile, polished or irregular precision parts that should not be tightly clamped or placed against hard support surfaces. In storage, sample transfer, inspection and display preparation, the membrane structure helps reduce surface rubbing, edge impact and part displacement while keeping the component visible without unpacking.

Key Features and Advantages

Suspended membrane holding helps protect finished or sensitive surfaces from direct hard-contact support.
The packed component remains visible through the clear shell, which improves identification, inspection and presentation efficiency.
The structure is suitable for irregular or easily displaced small parts that require centered positioning during storage and transfer.
Compared with direct-contact packaging, this format helps reduce shifting and local impact during routine handling and packing preparation.

APPLICATION SCOPE: Optical parts, crystal samples, dental prosthetics, watches, jewelry, miniature assemblies and other small delicate precision components that require stable suspended positioning during inspection, transfer and presentation.

PACKAGING: Store in a clean, dry area away from dust, heat and sharp objects that may damage the membrane surface. Before closing the box, confirm that the component outline fits the usable inner size of 52.5 x 52.5 x 21 mm and does not create excessive local pressure on the membrane.

IMPORTANT NOTICE: The standard version of this membrane box is non-latch. Optional latch closure is available on request. If the component has sharp edges, high point-load concentration or electrostatic sensitivity, please confirm the suitable shell material and closure configuration before ordering.

Constraints

Store in a clean, dry area away from dust, heat, and sharp objects to prevent membrane damage. Ensure the component outline fits the usable inner size and does not create excessive local pressure on the membrane.

Storage Environment: Store in a clean, dry area away from dust, heat, and sharp objects that may damage the membrane surface.
Component Fit Check: Before closing the box, confirm that the component outline fits the usable inner size of 52.5 x 52.5 x 21 mm and does not create excessive local pressure on the membrane.
Optional Anti-static Shell: If the component has electrostatic sensitivity, confirm the suitable shell material and closure configuration before ordering.

FAQ

What is the maximum component thickness that can be safely suspended in the Atomfair Membrane Box 75x75x25 mm without membrane overstretch?

The usable inner depth is 21 mm, so the component thickness must not exceed this dimension to avoid excessive local pressure on the membrane. The membrane is a transparent high-elastic film designed for gentle non-clamping retention; over-thick parts risk permanent deformation or membrane failure. For components with sharp edges or high point-load concentration, optional latch closure and custom shell material should be confirmed before ordering.

Can the Atomfair Membrane Box 75x75x25 mm be used for ESD-sensitive components without modification?

The standard version uses high-clarity PS shells, which are not inherently anti-static. For electrostatic-sensitive components, an anti-static shell material is available as an optional selection. The standard non-latch closure also does not provide a sealed ESD barrier. Users must specify the anti-static option and confirm closure configuration with the engineering sales team before ordering.

What handling precautions are required to prevent membrane damage during repeated opening and closing of the Atomfair Membrane Box?

The standard version has a non-latch closure, so the two-piece PS shells rely on friction fit. Repeated opening and closing should be performed in a clean, dry area away from dust, heat, and sharp objects that may puncture or tear the transparent high-elastic membrane. If frequent access is needed, the optional latch closure is recommended to reduce stress on the membrane edges and prevent accidental shell separation during handling.

Assessment

This 75x75x25mm membrane box uses transparent high-elastic films to suspend delicate optical, dental, or miniature components, reducing surface contact and impact damage while maintaining full visibility through clear PS shells; however, the standard non-latch closure and limited inner dimensions (52.5×52.5x21mm) require careful fit verification and may necessitate optional latch selection for secure transport.

Positive

Suspended membrane protection: The transparent high-elastic membrane holds components without direct hard-contact support, reducing surface rubbing, edge impact, and part displacement during storage, transfer, and inspection.
Clear shell visibility: The high-clarity PS shells allow the packed component to remain visible at all times, improving identification, inspection, and presentation efficiency without requiring unpacking.

Trade-offs

Non-latch closure standard: The standard version uses a non-latch closure, which may not secure the component during handling or transport; an optional latch closure must be requested separately for applications requiring positive retention.
Fixed inner size limitations: The usable inner dimensions are 52.5 x 52.5 x 21 mm, and components with sharp edges or high point-load concentration can create excessive local pressure on the membrane, requiring careful fit and material selection.
