Vacuum Forming Plastic Sheet Supplier

What We Manufacture in This Category

Vacuum forming converts heated thermoplastic sheet into thin-wall parts by drawing it over a mold under vacuum. We produce blister packs, trays, inserts, clamshells and structural covers in thicknesses from 0.25 mm to 2.5 mm, depending on material and grade.

Because we extrude our own sheet, we control thickness tolerance, surface quality and additive systems before forming. This matters for parts that must hold cavity depth, wall uniformity or optical clarity after thermoforming.

Our Vacuum Forming Product Range

Material Selection and Application Fit

Material choice determines clarity, stiffness, heat resistance, seal behavior and recyclability. We match the polymer and grade to the working environment rather than defaulting to a single resin.

• PS — good clarity and stiffness, low cost, suitable for disposable trays, toy inserts and electronics packaging. Flame-retardant, anti-UV and antistatic grades are available.
• PET — high strength and transparency, fully recyclable, no harmful gas emission during combustion. Suited to food-contact and precision tray applications.
• PP — food-safe, microwave-ready, wide temperature range from frozen storage through hot fill. The preferred choice for food and pharmaceutical packaging.
• Multi-layer and specialty formats — we can combine functional layers for barrier, optical or surface requirements.

Critical Specifications We Confirm Before Tooling

Vacuum forming quality is set by the heated sheet state, mold design and vacuum distribution. We define the following parameters with you before cutting tooling:

• Part geometry, draw depth and draft angles
• Sheet thickness and target wall thickness at deep draw points
• Forming temperature window for the selected polymer
• Mold type — plaster, electroplated copper or machined aluminum — matched to volume and surface requirement
• Vent hole placement and vacuum level
• Trim, punch and fold tolerances
• Seal or lidding method where applicable

Tooling and Production Capacity

Mold selection is a trade-off between tooling cost, surface quality, thermal conductivity and production volume. We advise on the right mold type for your batch size and finish requirement.

Our extrusion capacity includes PS lines in Suzhou and Zhongshan, PMMA lines, and multiple cutting, polishing, engraving, laser and printing units. This vertical integration shortens lead time and keeps sheet quality consistent across production batches.

Quality Control and Acceptance Testing

We test formed parts and the sheet they are made from in our own laboratory. Typical checks include:

• Dimensional measurement — 2.5D, thickness analysis, surface layer measurement
• Optical test — transmittance, haze, luminance and uniformity where relevant
• Reliability test — high/low temperature cycling, aging, abrasion and scratch resistance
• Mechanical test — hardness, drop impact, flame retardancy
• Material test — composition analysis and roughness

Acceptance criteria are agreed with you before production. We can supply inspection records and test data with each shipment.

Integration, Installation and Serviceability

Vacuum formed parts often interface with automated packaging lines, sealing equipment or assembly fixtures. We review the line interface during configuration so that stack height, nesting, feed orientation and seal zones match your equipment.

• Nesting and stacking geometry for automated handling
• Hang hole and feed tab placement
• Seal compatibility with card, foil or film lidding
• Fold line scoring depth for clamshell assembly
• Spare tooling and repeat order support

Information We Use to Configure Your Solution

To prepare a suitable proposal, we need the following project inputs. The more complete the data, the faster we can confirm tooling and pricing.

• Part drawing or 3D model, including tolerances
• Product to be packaged or protected — dimensions, weight, surface sensitivity
• Material preference or performance requirement (food contact, flame retardancy, antistatic, UV)
• Target thickness and wall uniformity requirement
• Annual volume and batch size
• Surface finish and color
• Sealing or lidding method, if applicable
• Line interface and automation requirements
• Compliance or documentation needs

Frequently Asked Questions

What materials can you vacuum form?

We form PS, PET, PP and multi-layer sheet formats, with thickness from 0.25 mm to 2.5 mm depending on grade. Functional grades include flame-retardant, anti-UV, antistatic, conductive, food-safe and recyclable options.

Can you produce food-contact packaging?

Yes. Our PP and PET vacuum forming products are designed for direct food contact, including microwave-ready and frozen food applications. We can provide material documentation to support your compliance review.

What is the typical lead time for a new tool?

Tooling lead time depends on mold type and part complexity. Plaster molds can be ready in days, while machined aluminum tooling requires longer. We confirm the schedule after reviewing the drawing and volume.

Do you support custom colors and surface finishes?

We offer customizable dimensions and colors. Surface finishes include glossy, matte, frosted and textured, depending on the mold and sheet specification.

How do you ensure wall thickness uniformity in deep draws?

We control heating uniformity, sheet sag and vacuum distribution. For deep draws, we may use plug assist or localized heating to maintain wall thickness at critical points.

Can you supply samples before mass production?

Yes. We support small-batch prototyping to validate fit, function and appearance before committing to production tooling.
