Wonderful PVAS-001

The PVAS-001 belongs in any prosthetic or orthotic workshop that laminates in a vacuum using resin. Laminated sockets remain a mainstay for below-knee and above-knee prostheses, upper-limb sockets, and many definitive devices, and each starts with PVA bags around a cast.

Hospital prosthetic departments and rehabilitation centres use the film daily for test and definitive sockets. Technicians cut a length, seal it into a sleeve, moisten it and draw it over the positive model as the inner bag. After stockinette, fibreglass or carbon reinforcement is applied, a second sleeve becomes the outer bag, the resin is poured, and the vacuum pulls the lay-up tight.

Private prosthetic clinics and orthotic laboratories use the same process for laminated orthoses, cosmetic covers and reinforced components. Training centres that teach prosthetic technology also rely heavily on PVA sheeting, since lamination is a core skill for every student technician.

High-volume laboratories benefit from the 100 m roll, which keeps the cutting table supplied through weeks of daily lamination. Smaller clinics and outreach workshops can hold the 50 m roll and still cut a sleeve for any socket size, from a child's below-knee socket to an adult transfemoral one.

Prosthetic and orthotic technicians, prosthetists and orthotists, handle it at the cutting table and the vacuum bench. Across all these settings, the workflow follows the same short sequence: cut, seal, moisten, stretch, pull the vacuum, and pour, with the PVA keeping the resin where it belongs and the socket clean on removal.

A Short, Repeatable Lamination Routine

Cut, seal, moisten, stretch and vacuum. The same steps work for every socket, so the routine is quick to learn and easy to repeat.

Clean Release From the Cast

The inner bag sits between plaster and resin. When the laminate has cured, the socket lifts away cleanly.

Stretch Over Complex Contours

Moistened PVA reaches into deep recesses and around flares at the brim. The film follows the cast closely, so the socket shape stays true.

Even Resin Under Vacuum

The outer bag holds resin around the lay-up and pulls tight under vacuum. Resin flows evenly through every reinforcement layer.

Smooth Surfaces Inside and Out

Film on both faces of the laminate leaves a smooth inner wall and a clean outer skin, reducing finishing work.

Any Socket From One Roll

Each sleeve is cut to length, so one roll covers below-knee, above-knee and upper-limb sockets.

Two Roll Lengths for Two Workloads

The 50 m roll suits smaller clinics, and the 100 m roll keeps busy laboratories supplied for longer.

Degradable Once Discarded

Wonderful describes the film as degradable in the natural environment, which suits workshops managing their lamination waste.

Ductile and Easy to Handle

Wonderful describes PVAS-001 as stretchy with good ductility. The film handles well at the bench and on the cast.

Polyvinyl Alcohol Film

Made of PVA, a film suited to vacuum resin lamination in prosthetics.

50 m Roll

Listed as 1.1 × 0.008 × 50 m, with a net weight of 6.65 kg.

100 m Roll

Listed as 1.1 × 0.008 × 100 m, with a net weight of 13 kg.

Softens With Moisture

The film becomes pliable when moist, ready to stretch over a cast.

Good Ductility

Stretches without tearing as it is drawn over contours.

Forms Inner Bags

Acts as the separating layer between the plaster model and the laminate.

Forms Outer Bags

Encloses reinforcement and resin during vacuum forming.

Cut to Length

Each sleeve is cut from the roll to suit the socket being made.

Sealable Into Sleeves

Edges and ends seal to form closed bags for the vacuum fitting.

Vacuum Forming Compatible

Used with vacuum forming of the resin socket.

Degradable Material

Wonderful describes the film as decomposing in the natural environment.

For Prosthetics and Orthotics

Serves laminated sockets, orthoses and reinforced components.

The PVAS-001 suits prosthetic and orthotic workshops that laminate resin sockets and need a dependable PVA supply on a roll. Its value lies in the workflow it makes routine: cut a sleeve, seal it, moisten it, stretch it over the cast, pull the vacuum and pour. The inner bag releases the socket cleanly from the plaster, and the outer bag spreads resin evenly through the reinforcement. High-volume laboratories suit the 100 m roll, and smaller clinics suit the 50 m roll. Each roll of film, 50 m or 100 m long, weighs 6.65 kg or 13 kg, respectively, when supplied.
