Functional Tea Bags in Sri Lanka: Contract Manufacturing Formats

Buyer's snapshot

Sri Lanka's tea bag exports reached 26.4 million kg in 2025, part of an 11-year high in value-added tea shipments (Tea Exporters Association Sri Lanka, 2025).

Four formats cover almost every local brief: pyramid, round paper (single-chamber), string-and-tag, and filter paper. Each has a different machine, MOQ, and cost profile.

Silk Foods Ceylon (SFC) private-labels Ceylon and herbal blends in all four formats on a BRCGS- and FSSC 22000 V6-audited line at Matale.

A gift-shop or supermarket-shelf tea bag needs SLSI clearance and a tri-lingual label; a complimentary in-room sachet does not.

Sri Lanka’s tea bag exports reached 26.4 million kilograms in 2025, part of an 11-year high in value-added tea shipments that made up 59 percent of total exports (Tea Exporters Association Sri Lanka, 2025). Functional and herbal blends, ashwagandha, hibiscus, lemongrass, moringa, are the fastest-growing slice of that category, for export and for the local Sri Lankan shelf alike. For a local FMCG brand owner launching a herbal or Ceylon tea range, the format decision (pyramid, round paper, string-and-tag, or filter paper) usually lands before the recipe does. It changes the machine, the MOQ, and the unit cost more than most brand owners expect.

Silk Foods Ceylon, a BRCGS- and FSSC 22000 V6-audited contract manufacturer at Silk AgTech Park in Matale, private-labels Ceylon and herbal tea blends in all four formats on request. The choice is rarely obvious. Pyramid bags read as premium but carry the highest tooling and per-sachet cost. Filter paper is the cheapest and fastest format to run, but it reads as basic next to a premium-positioned competitor. Round paper and string-and-tag sit between the two, with different trade-offs in cost, aroma protection, and packing speed.

What are the four functional tea bag formats?

Functional tea bags in Sri Lanka come in four working formats: pyramid, round paper (single-chamber, stringless), string-and-tag (enveloped), and filter paper (flat, double-chamber). Each format uses a different machine and material, which is why the format decision, not the recipe, is usually the first cost driver a local brand owner has to plan around.

Pyramid tea bags use a mesh material, certified plant-based mesh rather than nylon on the Matale line, heat-sealed into a three-dimensional sachet that gives whole-leaf tea more room to infuse. They are individually enveloped and typically packed in cartons of 15 to 25. The format reads as premium on a shelf or in a hotel gift-shop range, and it suits Ceylon black tea, green tea, and coarser herbal cuts best.

Round paper bags, sometimes called single-chamber or stringless bags, are a flat paper sachet with no string or tag, usually finished with a foil-lined outer caddy. They carry the lowest unit cost of the four formats, which is why high-turnover ranges, hotel in-room caddies among them, default to this format first.

String-and-tag bags add a printed tag and string to a paper sachet, individually enveloped in foil or paper. The extra components (string, tag, envelope) raise the per-unit cost above round paper, but the tag gives a brand a visible surface for its name, which matters where the sachet itself is part of the retail presentation.

Filter paper bags are the flat, rectangular, double-chamber sachet familiar from most supermarket tea aisles worldwide: uncoated cellulose paper, heat-sealed, sometimes foil-oversealed for a retail multi-pack. It is the fastest and cheapest format to run at volume, and the natural default for a brand testing a new blend before committing to a premium format.

Which format fits a first commercial run?

The four functional tea bag formats differ most on machine type, tooling lead time, and per-sachet cost, not on the tea itself. A brand launching a first commercial SKU typically picks round paper or filter paper for the lowest first-run cost, and reserves pyramid for a premium line extension once the core range is selling.

FormatMaterial and finishRelative first-run costTypical lead timeMachine fit
Filter paperUncoated cellulose paper, flat double-chamber, optional foil oversealLowest2 to 3 weeksDouble-chamber paper-bag machine; fastest cycle of the four
Round paper (single-chamber)Paper sachet, no string or tag, foil-lined outer caddyLowest2 to 3 weeksSame paper-bag machine family as filter paper
String-and-tagPaper sachet plus string, tag, individual foil or paper envelopeMid-range3 to 4 weeksPaper-bag machine plus tag-and-string and over-wrap stations
Pyramid (whole-leaf)Certified plant-based mesh, individually enveloped, carton of 15 to 25Highest4 to 6 weeksUltrasonic sealing machine; slower cycle, dedicated mesh changeover

Read the table by production step rather than by price tag alone. Filter paper and round paper share a machine family, so a brand consolidating two formats on one production block adds little changeover time. Pyramid’s ultrasonic sealing step is why its lead time runs longest. Mesh material and individual enveloping do not share tooling with the paper-bag formats, so a pyramid SKU is usually planned as its own production day rather than folded into a paper-format run.

Why one format rarely covers a full range

One Sri Lankan wellness brand approached Silk Foods Ceylon planning a six-SKU herbal tea range, all in pyramid format, because pyramid was the format its founder had seen on shelves abroad. Costing the full range against the format table changed the brief: the brand launched three core blends in round paper for modern-trade distribution and reserved pyramid for two hibiscus and moringa SKUs positioned for the diaspora gifting channel and hotel gift-shop racks. The recipe did not change. The format mix did, and it moved the launch budget back inside range.

That kind of format split is common enough that the R&D team now asks about the sales channel before the tea blend on a first-brief call, since the channel usually decides the format faster than the flavour does.

What certifications and labelling apply to a private-label tea bag SKU?

A tea bag SKU sold from a Sri Lankan retail shelf, gift shop, or e-commerce marketplace needs SLSI clearance and a tri-lingual label under the Food (Labelling and Advertising) Regulations 2022, enforced from January 2024. A complimentary sachet placed in a hotel room is a hospitality consumable and sits outside that requirement, a distinction most local brand owners miss on a first brief.

The certification stack for a retail tea bag SKU runs BRCGS, then FSSC 22000 V6, then USDA Organic and EU Organic where the blend carries an organic claim. SLSI, Sri Lanka Food Act 1980 compliance, and Department of Ayurveda registration follow, the last one where a herbal blend carries a traditional or Ayurvedic claim. Silk Foods Ceylon’s Matale facility is BRCGS- and FSSC 22000 V6-audited, with SLSI submission support built into a standard private-label engagement.

The label distinction that trips up a first-time brand owner is the retail-versus-hospitality line. Under the Ministry of Health’s Food (Labelling and Advertising) Regulations 2022, gazetted in February 2023 and enforced from 1 January 2024, a product sold at a gift shop, listed on a chargeable minibar, or offered as a takeaway box is a retail SKU. It needs SLSI clearance and a label carrying the common name in Sinhala, Tamil, and English, net weight in SI units, and the manufacturer’s SLS number.

A complimentary sachet left in a room as part of the stay is a hospitality service consumable, not a retail SKU. Brands planning a gift-shop range and an in-room amenity in the same order often assume one label clears both. It does not.

Which format fits which sales channel?

Format choice tracks the sales channel more reliably than it tracks the tea blend. The major Sri Lankan supermarket chains favour round paper and filter paper for cost. Sri Lankan hotel groups split between round paper for in-room amenity and pyramid for gift-shop retail. A Sri Lankan e-commerce marketplace and the diaspora gifting channel both reward pyramid and string-and-tag for shelf presentation.

For the major Sri Lankan supermarket chains, round paper and filter paper dominate because unit cost decides shelf price at that volume, and a shopper comparing two herbal tea boxes rarely pays a premium for mesh. Sri Lankan hotel groups typically run two formats in parallel: round paper for high-turnover in-room amenity, where cost per room-night matters most, and pyramid or string-and-tag for the gift-shop range, where the format is part of what a guest pays to take home.

A Sri Lankan e-commerce marketplace listing and the diaspora gifting channel reward the same instinct. A buyer scrolling a product photo responds to a visible tag or a translucent pyramid sachet more than to a sealed paper caddy, which is why those two formats convert better in those channels even at a higher unit cost.

Frequently asked questions

Does Silk Foods Ceylon offer contract manufacturing for functional tea bags?

Yes. Silk Foods Ceylon formulates and packs Ceylon and herbal tea blends across pyramid, round paper, string-and-tag, and filter paper formats at its BRCGS- and FSSC 22000 V6-audited Matale facility. Sample turnaround typically runs 2 to 4 weeks for an existing blend, and 6 to 10 weeks when R&D/NPD locks a new recipe first.

What is the difference between a pyramid tea bag and a round paper tea bag?

A pyramid tea bag uses a certified plant-based mesh sealed into a three-dimensional sachet that gives whole-leaf tea more infusion room, individually enveloped in cartons of 15 to 25. A round paper (single-chamber) bag is a flat paper sachet with no string or tag, usually foil-caddy packed, at a lower unit cost.

Do private-label tea bags need SLSI clearance in Sri Lanka?

Yes, when the tea bag is sold as a retail SKU: a supermarket shelf, gift-shop item, chargeable minibar product, or marketplace listing. SLSI clearance and a tri-lingual label under the Food (Labelling and Advertising) Regulations 2022 apply. A complimentary in-room sachet is a hospitality consumable and is exempt.

What certifications apply to a herbal tea bag carrying an Ayurvedic claim?

Herbal tea blends using regulated Ayurvedic claim language need Department of Ayurveda registration alongside SLSI clearance and Sri Lanka Food Act 1980 compliance. The cert stack for such SKUs runs BRCGS, FSSC 22000 V6, SLSI, Food Act compliance, then Department of Ayurveda registration where the claim applies.

How Silk Foods Ceylon can help

For local FMCG brands shifting from in-house production to professional contract manufacturing, Silk Foods Ceylon (SFC) operates a 10,000 sq ft cellular-manufacturing facility in Matale. The line runs pyramid, round paper, string-and-tag, and filter paper tea bag formats on a single BRCGS- and FSSC 22000 V6-audited cert stack. Sample turnaround typically runs 2 to 4 weeks for an existing blend, and 6 to 10 weeks when R&D/NPD locks a new recipe first. SLSI submission support sits inside the standard engagement, and multiple formats or SKUs consolidate onto one production block rather than separate minimum orders.
