HarborPeak BPA-Free Silicone Collapsible Cup Set

What This Cup Set Is Built For

The HarborPeak BPA-Free Silicone Collapsible Cup Set is a six-piece drinkware kit molded from food-grade silicone tested to LFGB standards. Each cup collapses from a 250 ml drinking height down to roughly 18 mm, which lets a full set stack inside a drawer, backpack, or breakroom shelf at a fraction of the footprint of rigid tumblers. The material holds its shape from -40°C up to 230°C, so the same cup can hold boiling water for tea and then go straight into the freezer for portion storage without warping or releasing odor.

For distributors selling into the German and UK markets, the LFGB rating is the relevant compliance anchor. The German Food, Consumer Goods and Feed Code requires LFGB testing for any silicone article that contacts food, and this set carries that certification. UK buyers sourcing after Brexit can reference the retained EU regulation 1935/2004 framework; the LFGB migration test data supports that documentation chain as well.

Material and Temperature Performance

Each cup is pressed from a single piece of platinum-cured silicone. There are no glued seams or plastic inserts in the drinking contact zone, which removes the common failure point where heat separates a bonded ring from the cup wall. The silicone is rated for continuous use across a -40°C to 230°C range.

The -40°C lower bound covers standard household and commercial freezer compartments. The 230°C upper bound covers boiling water (100°C at sea level) with a safety margin, and also permits short-term oven contact if a cup is used as a portion mold. The cups are not rated for direct flame or stovetop burner contact.

Dishwasher and Stacking Behavior

Every cup in the set is dishwasher-safe on both top and bottom racks. The silicone surface does not carry a powder coating or paint layer, so repeated hot-wash cycles do not strip a finish the way they can on coated steel tumblers. The cups stack vertically when expanded, and nest compactly when collapsed. A six-cup set in collapsed form occupies roughly the shelf space of a single rigid 350 ml tumbler.

Care notes

• Silicone can pick up residual soap scent in dishwashers with heavy pre-rinse aid use; a plain hot rinse cycle resolves this.
• Do not place in direct contact with a gas flame, induction cooktop surface, or oven heating element.
• Boiling-water contact is within spec; prolonged simmering on a heat source is not.
• Cups can be sterilized by immersion in boiling water for 2 to 3 minutes.

Compliance and Documentation

The set carries LFGB food-contact certification, which is the baseline requirement for silicone drinkware entering the German market. For the United Kingdom, the retained regulation 1935/2004 food contact materials framework applies; the LFGB overall migration and specific migration test data can be supplied to support a UK Technical File. For the United States, the silicone material is produced to be consistent with FDA 21 CFR 177.2600 requirements for rubber articles intended for repeated food contact. HarborPeak can provide the migration test reports and a declaration of compliance on request.

Who Buys This Product

This set is purchased by three main buyer profiles. Outdoor and camping retailers in Germany and the UK stock collapsible silicone cups as a space-saving kit for backpackers and caravan owners. Corporate gifting buyers order the set with a custom logo for event giveaways, since the collapsed cup fits inside a standard mailer and keeps shipping cost low. Food-service operators purchase the cups as portion-measure and tasting vessels in commercial kitchens, where the dishwasher-safe silicone holds up to repeated wash cycles better than coated steel.

Customization and OEM ODM

HarborPeak accepts OEM and ODM orders for this set. The standard offering includes a range of solid colors; Mint Green is the default catalog color. Custom Pantone-matched colors are available subject to a per-color minimum order quantity. A custom logo can be applied via pad printing or debossed molding on the cup exterior. Packaging options include individual poly bags, recycled kraft boxes, and custom retail boxes.
