Membrane Box 80 x 42 x 21 mm

Description

Membrane Box 80 x 42 x 21 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 80 x 42 x 21 mm, and the usable inner size is 65 x 25 x 16 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 65 x 25 x 16 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 the membrane box in a clean, dry area away from dust, heat, and sharp objects to prevent membrane damage. Ensure the component fits within the usable inner size of 65 x 25 x 16 mm and does not exert excessive local pressure on the membrane.

Environmental Storage: Store in a clean, dry area away from dust, heat, and sharp objects that may damage the membrane surface.
Component Size Compatibility: Confirm that the component outline fits the usable inner size of 65 x 25 x 16 mm before closing the box.
Pressure Limitation: Ensure the component does not create excessive local pressure on the membrane to avoid deformation or damage.
Sharp Edge and Electrostatic Sensitivity: For components with sharp edges, high point-load concentration, or electrostatic sensitivity, confirm suitable shell material and closure configuration before ordering.

FAQ

What is the performance trade-off between the standard non-latch closure and the optional latch closure for the AF-MB-8020 membrane box?

The standard non-latch closure provides quick access and clear visibility for stationary storage and inspection, but for transport or handling that may cause component displacement, the optional latch closure is recommended. The product datasheet notes that for components with sharp edges or high point-load, the latch closure should be confirmed to secure retention. The choice depends on whether the priority is ease of access or secure closure during movement.

When is the optional anti-static shell material required for the membrane box?

The optional anti-static shell material is required when the component exhibits electrostatic sensitivity or when the operating environment demands static protection. The product specification explicitly advises confirming the suitable shell material if the component has electrostatic sensitivity. The standard high-clarity PS shell does not provide anti-static properties, so for sensitive electronics or precision assemblies, the anti-static option should be chosen.

What storage conditions must be maintained to prevent damage to the membrane films in the AF-MB-8020 box?

The membrane box must be stored in a clean, dry area away from dust, heat, and sharp objects that could puncture or degrade the transparent high-elastic membrane films. Before closing, the component outline must fit the usable inner size of 65 x 25 x 16 mm to avoid excessive local pressure on the membrane. These conditions ensure the membrane retains its elastic properties and protective function.

Assessment

The Atomfair Membrane Box 80 x 42 x 21 mm (SKU: AF-EI-A-MBOX-8020-N010) is a transparent PS shell with high-elastic membrane films designed for suspended, non-clamping retention of fragile, polished, or irregular precision parts, offering visible protection during storage and transfer but requiring careful component sizing and handling to avoid membrane damage.

Positive

Suspended membrane protection for delicate surfaces: The transparent high-elastic membrane films hold components without direct hard-contact support, reducing surface rubbing, edge impact, and displacement for fragile, polished, or irregular precision parts.
Visible inspection without unpacking: The high-clarity PS shell and transparent membrane allow full visibility of the packed component, improving identification, inspection, and presentation efficiency during storage and sample transfer.

Trade-offs

Membrane vulnerable to sharp edges and point loads: Components with sharp edges or high point-load concentration may damage the membrane surface; the standard non-latch closure may not secure such items, requiring optional latch closure and careful shell material selection.
Limited usable inner dimensions and environmental sensitivity: The usable inner size of 65 x 25 x 16 mm restricts component fit, and the membrane requires storage away from dust, heat, and sharp objects to prevent damage, adding handling constraints.
