When evaluating alternatives to plastic release liners used with lifting bra tape, the available product information points to a different approach: non-adhesive silicone nipple covers. Since these covers have no adhesive layer, they do not require a release liner. The information provided does not identify another liner material for adhesive bra tape.
Made from 100% solid silicone, these nipple covers provide discreet coverage without adhesive. They are offered in 8 cm and 10 cm sizes and in nude, khaki, brown, and coco. Buyers can choose OPP bags or customized packaging, and samples are available. Care instructions specify hand washing only.
A release liner protects the adhesive surface of an adhesive product before use. The non-adhesive silicone covers described here take another route: they are supplied without an adhesive layer, so a liner is not part of the documented product configuration. The supplied specifications do not name a substitute liner, coating, or backing for lifting bra tape.
Xinrui describes use across summer and casual wear, weddings, evening and party outfits, swim and vacation clothing, and fitness or yoga apparel. These applications include strapless, off-shoulder, deep-V, fitted, and lightweight garments. A US online apparel seller has also sourced invisible covers for camisoles, off-shoulder and strapless tops, deep-V blouses, fitted tees, wedding gowns, and formalwear. That example illustrates demand for invisible coverage; it does not verify a different release-liner material.
The company lists BSCI and ISO 9001 certifications and says it inspects incoming materials, production in progress, and finished goods.

| Product or option | Information provided | Release liner details |
|---|---|---|
| Non-adhesive silicone nipple covers | 100% solid silicone; 8 cm and 10 cm; nude, khaki, brown, and coco | No adhesive layer or liner is specified |
| Adhesive lifting bra tape | The product information mentions lifting breast tape and adhesive nipple-cover styles, including X3 adhesive technology | No plastic-liner substitute is identified |
| Packaging options | OPP bag or customized packaging; samples are available | Packaging information does not specify liner materials |
The information identifies non-adhesive, 100% solid silicone nipple covers as an alternative product format. It does not specify another liner material for adhesive lifting bra tape.
No adhesive is listed for the non-adhesive covers, so the described product does not use an adhesive layer or release liner.
The stated details include solid silicone construction, 8 cm and 10 cm sizes, four color options, OPP or customized packaging, sample availability, and hand-wash-only care.
For buyers looking to avoid a plastic release-liner system, the documented option is a non-adhesive cover rather than a replacement liner substrate. Before selecting it, confirm that a non-adhesive design meets your requirements for lift, attachment, and garment use. You can then assess the available sizes, colors, packaging, samples, and quality-inspection process.
