Round Membrane Box Dia. 75 x 16 mm

Description

Round Membrane Box Dia. 75 x 16 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. 75 x 16 mm, and the usable inner size is Dia. 65 x 12 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. 65 x 12 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

This membrane box requires storage in a clean, dry environment away from dust, heat, and sharp objects to prevent membrane damage. Components must fit within the usable inner dimensions and avoid excessive local pressure on the membrane to maintain structural integrity.

Storage Environment: Store the box in a clean, dry area away from dust, heat, and sharp objects that may damage the membrane surface.
Component Fit: Before closing the box, confirm that the component outline fits the usable inner size of Dia. 65 x 12 mm and does not create excessive local pressure on the membrane.
Sharp Edge and Electrostatic Sensitivity: If the component has sharp edges, high point-load concentration, or electrostatic sensitivity, confirm suitable shell material and closure configuration before ordering.
Membrane Integrity: The transparent high-elastic membrane films are susceptible to damage from sharp objects and excessive pressure, requiring careful handling.
Optional Customization: Anti-static shell material, custom shell color, and optional latch closure are available to address specific component requirements.

FAQ

How does the transparent high-elastic membrane film in the AF-MB-R7516 balance component retention and visibility compared to rigid inserts?

The membrane film provides gentle non-clamping retention that avoids direct hard-contact support, reducing surface rubbing and edge impact while maintaining full visibility through the clear PS shell. The usable inner diameter of 65 mm and depth of 12 mm define the component size limit; however, excessive local pressure on the membrane from sharp edges or point loads may require an optional latch closure or alternative shell material.

Can the AF-MB-R7516 membrane box accommodate components with sharp edges or electrostatic sensitive parts?

The standard version uses non-latch closure and standard PS shell, so components with sharp edges or high point-load concentration may cause excessive local pressure on the membrane and require the optional latch closure. For electrostatic sensitive parts, an anti-static shell material option is available. It is recommended to confirm suitable shell material and closure configuration before ordering.

What storage and handling conditions are required to maintain the integrity of the AF-MB-R7516 membrane box and its contents?

The box should be stored in a clean, dry area away from dust, heat, and sharp objects that may damage the membrane surface. Before closing, confirm that the component outline fits the usable inner size of Dia. 65 x 12 mm. The membrane film is high-elastic and transparent, so avoid contact with sharp tools to prevent tearing. Pack quantity is 5 pieces per order.

Assessment

This round membrane box provides non-contact suspended protection for circular fragile components up to 65 mm diameter, using transparent PS shells and elastic membrane films. The design reduces surface abrasion and impact during handling, but requires careful size matching and optional latch closure for secure containment.

Positive

Suspended membrane protection: The membrane suspension prevents direct hard-contact support, protecting finished or sensitive surfaces from rubbing, edge impact, and displacement during storage and transfer.
Visible packaging without unpacking: The clear PS shell keeps the component visible for identification, inspection, and presentation, reducing handling and improving workflow efficiency.

Trade-offs

Non-latch standard closure: The standard version does not include a latch, which may lead to accidental opening during transport or handling. An optional latch closure is available upon request.
Component size and shape constraints: Components must fit within the usable inner dimensions of Dia. 65 x 12 mm and avoid sharp edges or high point loads that could cause excessive local pressure on the membrane film.
