Resposta rápida: compradores escolhendo additives for shrink sleeve inks usually get a faster first shortlist when they separate three different additive jobs instead of asking one product to solve every packaging-print problem at once. CHLUMIWE® 2100 should move first when the main issue is film-surface wetting, spread, or cleaner laydown on shrink-sleeve film. CHLUMIAG® 3501 deserves earlier review when the buyer needs a broader antiaderente, sleeve-web handling, ou downstream converting compatibility route. CHLUMIAF® 3062 belongs earlier when the system already looks directionally right but foam, entrained air, or circulation-side instability keeps undermining production or print quality.
That is the commercially useful split. This page is not another general label-ink overview. It is a narrower CHLUMICRYL® application page para compradores que já conhecem o projeto é um shrink sleeve ink job and need a clearer first screen before requesting samples.
Why shrink sleeve inks deserve their own additive page
Longchang já possui páginas ativas para label ink additives, flexographic ink additives, gravure ink additives, inkjet ink additives, e metal packaging ink additives. Those pages solve broader label, process, or substrate questions.
A shrink-sleeve project creates a tighter buyer question: is the first additive decision mainly about getting the ink to wet and spread on shrink film, about improving print-side handling and anti-blocking during rewinding and converting, or about suppressing foam and trapped air during manufacture and press use? That is a different application question because sleeve work usually combines film surfaces, tight winding and handling windows, and pressure to keep the printed web stable before the sleeve is finally applied.
The broader industry framing here is conservative. External shrink-sleeve and packaging-ink references commonly separate film wetting, slip / blocking / scuff-sensitive handling, e efficient defoaming as different formulation jobs instead of one single additive decision. The product-specific facts below still stay tied to current Longchang-supported product pages.
O que os fatos atuais, com o apoio da empresa, já diferenciam
- CHLUMIWE® 2100 is supported by Longchang for tintas de impressão, vernizes de sobreimpressão, e tintas para impressoras jato de tinta, with recommended dosage at 0,1% a 1,0%, addition during grinding, stirring, ou after production, optional solvent pre-dilution, and applicability across UV, solvente, e sistemas à base de água.
- CHLUMIAG® 3501 is supported by Longchang as a polissiloxano modificado multicomponente that can be added at any stage and used across UV, solvente, e sistemas à base de água. The current company-supported page directly lists tintas de impressão, tintas para impressoras jato de tinta, vernizes de sobreimpressão, revestimentos de liberação, e anti-sticking-agent use.
- CHLUMIAF® 3062 é o rota antiespumante inicialLongchang oferece suporte a isso para tintas de impressão com uma dosagem recomendada de 0,1% a 0,5% of total formulation, broad UV, solvente, e à base de água applicability, and the practical watchpoint that if solvent dilution is used, stability and defoaming performance should be tested first.
That is enough product-level separation to build a real shortlist for shrink sleeve inks without inventing unsupported packaging claims.
Tabela de comparação rápida: qual rota merece aparecer em primeiro lugar?
| Buyer priority in shrink sleeve inks | Melhor primeira rota | Por que ele deve ser o primeiro? | Posto de observação principal |
|---|---|---|---|
| Poor shrink-film contact, weak spread, or a drawdown that still looks like a wetting-first problem | CHLUMIWE® 2100 | Longchang directly lists printing inks and overprint varnishes on the product page and supports broad system fit with flexible addition timing | Keep the screening job focused on wetting and spread instead of expecting one additive to solve every downstream web-handling issue |
| Broader anti-sticking pressure, print-face handling, or sleeve-web converting compatibility after printing | CHLUMIAG® 3501 | The product page directly combines printing-ink use with overprint varnishes, release coatings, and anti-sticking-agent positioning | Because it is a broader compatibility route, define the real KPI before screening so the result stays interpretable |
| Persistent foam, entrained air, or circulation-side instability during ink manufacture, letdown, or printing | CHLUMIAF® 3062 | Longchang directly supports it as a printing-ink defoamer with a dedicated dosage window and broad system applicability | If solvent dilution is used, stability and defoaming performance should be checked before scale-up |
When CHLUMIWE® 2100 is the better first move
2100 should move to the front when the shrink-sleeve project still looks like a wetting and spread problem. This is often the cleaner first route when the printed film surface is not accepting the ink the way the team expects, the drawdown still shows weak first contact, or the lab needs a simpler benchmark before moving into broader anti-blocking and handling tradeoffs.
The current Longchang page gives 2100 a useful operating window for that job. It supports 0,1% a 1,0% dosage, can be added during grinding, stirring, or after production, and can be diluted with water, alcohols, alkanes, and aromatics. The same page directly lists tintas de impressão e vernizes de sobreimpressão among its application scenarios.
- Melhor uso na primeira tela: shrink-film wetting, spread, and initial laydown screening
- Orientações sobre a dosagem: 0,1% a 1,0% da formulação total
- Ajuste do sistema: Sistemas à base de UV, solventes e água
- Commercial reason to shortlist it: it gives a cleaner first answer when the buyer still needs basic film contact to improve before testing broader anti-sticking or foam-control routes
In short, 2100 is the better first move when the real question is still how the ink meets the shrink-sleeve film.
When CHLUMIAG® 3501 is the better first move
3501 deserves earlier review when the project is no longer only about first contact. It is the stronger route when the buyer needs a broader antiaderente, release-oriented, ou compatibilidade do lado de impressão path that can still sit naturally inside a shrink-sleeve ink branch.
The current Longchang page is clear here. 3501 is not only listed for tintas de impressão; it is also publicly positioned for tintas para impressoras jato de tinta, vernizes de sobreimpressão, revestimentos de liberação, e anti-sticking-agent use. It can be added at any stage and used across UV, solvente, e sistemas à base de água.
- Melhor uso na primeira tela: broader sleeve-web handling questions, including anti-sticking, print-face release behavior, and converting-adjacent compatibility
- Lógica de adição: can be added at any stage or later
- Ajuste do sistema: Sistemas à base de UV, solventes e água
- Commercial reason to shortlist it: it is the cleaner route when the buyer needs a wider print-and-converting compatibility path instead of only a wetting correction
That makes 3501 the better first move when the problem sits more in rewind handling, downstream compatibility, or print-face anti-sticking behavior than in basic spread.
When CHLUMIAF® 3062 is the better first move
3062 should move first when the shrink-sleeve ink project already has a plausible wetting route but the system keeps failing because of foam, entrained air, ou poor process stability. That is a different job from improving first contact or tuning print-side handling. It is also one that can waste a lot of development time if the team keeps screening more surface additives before solving the foam problem.
Longchang supports 3062 as a polissiloxano modificado com poliéter defoamer for tintas de impressão, with a recommended dosage at 0,1% a 0,5% of total formulation and applicability across UV, solvente, e sistemas à base de água. The product page also adds a practical note: if solvent dilution is used, the team should first verify stability and defoaming performance.
- Melhor uso na primeira tela: foam control, air-release management, and process-side stability in shrink-sleeve ink workflows
- Orientações sobre a dosagem: 0.1% to 0.5% of total formulation
- Ajuste do sistema: Sistemas à base de UV, solventes e água
- Atenção principal: test solvent-dilution stability before scale-up if dilution is part of the process plan
So 3062 is the better first move when the project is being limited by gas management, not by missing wetting or print-side compatibility.
Como os compradores devem escolher antes de solicitar amostras
1. Start with the first visible bottleneck
If the shrink film still is not accepting the ink cleanly, start with 2100. If the real issue is broader anti-sticking, handling, or downstream converting compatibility, move 3501 earlier. If the project is already being damaged by foam or trapped air, move 3062 up.
2. Keep the sleeve workflow visible
This page is intentionally narrower than the broader label-ink page. A shrink-sleeve job has more film-specific pressure around web handling, winding, and keeping the printed sleeve practical before final application. That makes the first additive screen more application-specific than a general label page.
3. Do not force a defoamer into a wetting job
If the buyer has not yet solved basic film contact, a wetting-first route usually teaches more than jumping straight to a defoamer. The opposite is also true: once the real problem is foam and air release, a new wetting additive may only add noise to the first screen.
4. Use the watchpoint, not only the headline benefit
2100 is broad, but that does not mean it is the best first route for every downstream issue. 3501 offers a wider handling and compatibility route, but the KPI still needs to stay clear. 3062 can be diluted, but the team should verify stability and defoaming first. Those practical notes often decide the better first sample more than the product family name.
5. Mantenha a primeira rodada equilibrada.
For many buyers, one rota molhada, um broader sleeve-handling compatibility routee um rota antiespumante inicial teach more than screening too many nearby additives at once.

PERGUNTAS FREQUENTES
Which additive should I screen first if a shrink sleeve ink is not spreading cleanly?
Usually CHLUMIWE® 2100, because it is the cleaner wetting-first benchmark when the real problem is shrink-film contact and spread.
When should 3501 move ahead of 2100?
3501 should move ahead when the ink already wets reasonably well but the project still needs a broader anti-sticking, handling, or downstream converting compatibility route.
When should 3062 move ahead of the other two?
3062 should move ahead when persistent foam, entrained air, or process-side instability is the main barrier to acceptable print quality or manufacturing stability.
Can one of these additives solve every shrink sleeve ink issue?
No. Their supported first-screen logic is different enough that buyers should not treat them as interchangeable. The faster route is to identify whether the problem starts at wetting, web handling, or foam control.
Need a faster shortlist for shrink sleeve inks?
Se sua equipe estiver presa entre film-surface wetting, print-side anti-sticking and sleeve-web handling, e controle de espuma, define the real first-screen job before requesting samples. That usually shows much faster whether CHLUMIWE® 2100, CHLUMIAG® 3501, or CHLUMIAF® 3062 deserves the first round.
