Description

Round Membrane Box Dia. 80 x 40 mm

Membrane-supported component protection

Product Overview

This round membrane box is made with upper and lower high-clarity PS shells and transparent high-elastic membrane films. The outer size is Dia. 80 x 40 mm, and the usable inner size is Dia. 69 x 36 mm, making it suitable for compact circular 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.
  • Round formats are useful for circular or easily displaced 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: Round optical parts, circular samples, crystals, watch components, jewelry parts and other delicate precision items 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 Dia. 69 x 36 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.

This document outlines the environmental and compatibility constraints for the Atomfair round membrane box model AF-MB-R8040. Adherence to these constraints ensures component protection and membrane integrity.

  • Storage Environment: Store the box in a clean, dry area away from dust, heat, and sharp objects to prevent membrane damage.
  • Component Size Compatibility: Before closing, confirm that the component outline fits within the usable inner size of Dia. 69 x 36 mm to avoid excessive local pressure on the membrane.
  • Edge Sensitivity and Closure: If the component has sharp edges or high point-load concentration, confirm suitable shell material and closure configuration with the supplier.

What is the maximum recommended component height for the AF-MB-R8040 round membrane box to avoid excessive membrane pressure?

The usable inner size is Dia. 69 x 36 mm, so components should not exceed 36 mm in height. The packaging note confirms that the component outline must fit these dimensions and that excessive local pressure on the membrane must be avoided.

Is the standard round membrane box suitable for electrostatic-sensitive devices without modification?

The standard shell material is high-clarity PS, which does not have anti-static properties. The important notice advises confirming a suitable shell material and closure configuration if the component has electrostatic sensitivity, and an optional anti-static shell material is listed as an available selection.

What storage and handling precautions are necessary to prevent membrane damage in the round membrane box?

The box should be stored in a clean, dry area away from dust, heat, and sharp objects that could damage the membrane surface. Additionally, components with sharp edges or high point-load concentration may require confirmation of suitable shell material and closure configuration before use.

The AF-MB-R8040 round membrane box offers suspended, non-clamping retention for delicate circular components such as optical filters and crystals, using transparent PS shells and high-elastic membrane films. Its design prioritizes surface protection and visibility, but requires careful component sizing to avoid membrane stress and lacks a latch in the standard configuration, which may affect secure closure for certain handling scenarios.

Positive

  • Suspended membrane protection: The high-elastic membrane film holds components without hard-contact support, reducing surface rubbing, edge impact, and displacement during storage, transfer, or inspection.
  • Clear shell for visual inspection: The transparent PS shell and membrane allow the packed component to remain visible without unpacking, improving identification and inspection efficiency in lab or display settings.

Trade-offs

  • Standard non-latch closure: The box comes with a non-latch closure in standard configuration, which may not provide secure sealing for applications requiring restricted access or protection against accidental opening.
  • Component fit and pressure limits: Components must fit within the usable inner size (Dia. 69 x 36 mm) and avoid sharp edges or high point-load concentration to prevent excessive local pressure on the membrane or electrostatic sensitivity issues.
