01
Engineering thermoplastics selection
Polycarbonate, ABS, PC blends and specialty resin requests are reviewed against impact, optical clarity, dimensional stability, flame performance and downstream finishing requirements.

Silgan — Silgan: Build Circular Progress into the Material Brief
Start with service conditions, processing constraints and the evidence your approval team needs. The result is a clearer route to grade, component or converted-product review.
Connected grade review
Every resin recommendation starts with process, property and documentation context.
02
Processing-window alignment
Injection molding, extrusion, thermoforming and sheet conversion conversations include melt flow, shrinkage, color package, regrind practice and expected lot-to-lot control.
03
Documentation before sample chaos
Datasheets, declarations, food-contact questions, customer restricted substance lists and distributor paperwork are mapped early, giving buyers a cleaner route from material shortlist to production qualification.
Specification comparison
Two common Silgan inquiry paths need different evidence.
| Decision Area | Polycarbonate / PC Blend | Polyolefin / Packaging Resin |
|---|---|---|
| Performance target | Impact resistance, clarity, dimensional stability, heat performance and flame rating. | Stiffness, sealing behavior, melt strength, density, barrier support and cycle efficiency. |
| Processing data | Mold temperature, wall thickness, gate design, drying condition and cosmetic surface expectation. | Extrusion rate, blown film or sheet setup, thermoforming depth, cooling and trim recovery. |
| Compliance review | RoHS, REACH, UL files, medical suitability questions and customer restricted substances. | Food-contact path, recycling compatibility, regional packaging rules and migration evidence. |
| Commercial planning | Grade continuity, color match, sample plaque timing and distributor coverage. | Annual volume, pallet format, film or container launch window and supply buffer. |
Compliance Signals
Certification language that belongs in the sourcing file.
ISO 9001 quality system review
Used as the baseline for controlled material communication, corrective action discipline, and repeatable customer documentation.
FDA 21 CFR 177 screening
Relevant when plastic films, elastomers, or tubing may contact food, beverage, pharmaceutical, or processing media.
REACH and RoHS declarations
Requested early for European equipment, electronics, and packaging buyers managing restricted substances and supplier evidence.
USP Class VI / ISO 10993 pathways
Considered for medical and bioprocess tubing programs that need biological reactivity or contact-risk evaluation.
Polymer resins and plastic processing products.
SDS, COA, regulatory notes, and trial records.
Fast response for grade shortlist and quote requests.
Commercial and technical details stay together.
Bring Silgan a real application file, not a generic material name.
Share the part function, processing method, target properties, compliance region and forecast volume. The review can start with facts the first time.
