Picture a packaging materials supplier on the flight home from the show. There are a dozen business cards in a jacket pocket, a phone full of booth photos, and a spreadsheet of companies that never got a visit. Within a week, the event will feel like old news to everyone who exhibited.
This guide shows you how to follow up with PACK EXPO exhibitors in an order that makes sense: who to contact first, which signals to look for, when to send each message and how to stay compliant. It works whether you walked the 2026 PACK EXPO in person or are working from the sidelines.
PACK EXPO International is a trade-only show for the packaging and processing industry, organized by PMMI, the Association for Packaging and Processing Technologies. It is held in Chicago every two years and brings machinery makers, materials suppliers and automation providers together with the buyers, engineers and plant managers who source from them. PACK EXPO exhibitors serve more than 40 vertical markets, including food and beverage and pharmaceutical packaging, so visitors can compare suppliers and see new equipment in one place.
Follow up within the first few days, while the conversation is still fresh on both sides. After a four-day show with roughly 2,600 exhibitors, booth teams return to full inboxes, open sales requests and travel reports. A message that points to a specific moment from the show gets read. A generic one gets filed away.
The goal of week one is not to close anything. It is to be remembered, to be useful and to set up a short next step, such as a call or a sample request. Everything below is built around that goal.
Split your list by how much context you already have, because context decides both the channel and the tone.
| Tier | Who they are | First touch | Timing | Tone |
|---|---|---|---|---|
| A | Exhibitors you spoke with at the show | Personal email that references the conversation, then a LinkedIn note | Within 1-2 business days | Specific, short, one clear ask |
| B | Exhibitors you did not meet but who show a clear buying signal | Email to the right role, opening with one point about their business | Days 3-7 | Helpful, no pitch in the first line |
| C | Exhibitors that fit your ideal customer profile (ICP) but show no signal yet | Light-touch sequence or nurture list | Weeks 2-4 | Educational, low pressure |
Tier A is usually the smallest group and the easiest to handle. Most of the work, and most of the missed opportunity, sits in Tiers B and C: companies that match what you sell but that you never reached on the floor.
Imagine a labeling software vendor with 12 Tier A conversations, 60 Tier B companies and a few hundred Tier C. Treating all of them the same way would either overwhelm the sales team or waste the warm conversations.
A buying signal is any visible sign that an exhibitor is changing something your product could support. Packaging and processing shows produce plenty of them. Look for these:
New machine or line launches. Exhibitors that debuted equipment often need materials, integration partners, service providers and training around it.
Sustainability announcements. A move toward recyclable or reusable materials can create demand for testing, converting and supply chain changes.
Automation and robotics pushes. Companies adding automation often look at software, sensors, safety components and maintenance services.
Expansion news. New facilities, acquisitions or hiring for engineering and operations roles point to growth plans.
A new vertical. A company moving from food and beverage into pharmaceutical or personal care packaging faces new documentation and compliance needs.
You can find these signals in exhibitors’ own press releases, in PACK EXPO news posts and trade publication coverage of the PMMI PACK EXPO show, on LinkedIn company pages and on job boards. Spend ten minutes per Tier B company, not an hour. Record one signal and one sentence of context in your CRM so the first message writes itself.
Imagine a supplier of conveyor guarding that notices a Tier B exhibitor announcing a new filling line. That one fact turns a cold email into a relevant one: “I saw the new line you launched, and guarding is usually a late-stage question on projects like that.” The message is short, specific and easy to answer.
Booth staff at a show are often sales representatives. The person who decides whether your product fits is usually somewhere else in the company, and who that is depends on what you sell.
| If you sell | Start with | Then try |
|---|---|---|
| Machine components, spare parts or service | Maintenance or plant engineering lead | Operations manager |
| Packaging materials | Packaging engineer or procurement | Sustainability or product development |
| Software, sensors or automation | Operations or automation engineering | IT or continuous improvement |
| Marketing, logistics or booth services | Marketing or events lead | Sales leadership |
Keep PACK EXPO attendees as a separate list from exhibitors. Attendees are buyers, engineers and plant managers who came to source equipment, and they need a different message than a company that paid for a booth.
If all you have for many exhibitors is a booth contact or a general inbox, this is the point where a custom contact list of PACK EXPO International 2026 exhibitors, filtered by industry segment and job function, can cut the research time. Your team then spends the week writing instead of hunting for names.
Three to four touches over about a month is enough for most B2B follow-up. More than that starts to feel like pressure.
Day 1-2: a personal note to Tier A that references something said at the booth.
Day 5-7: the first message to Tier B, led by the buying signal you found.
Day 12-14: a second message with something useful, such as a short guide, a relevant example you actually have or a useful comparison.
Day 25-30: a brief close-the-loop note that makes it easy to say “not now”.
Stop earlier if the person replies or asks you to stop.
Keep the first message under about 120 words and build it from five parts:
Context: why you are writing, either the conversation or the announcement you noticed.
Relevance: one sentence linking their situation to a problem you help with.
Value: one useful resource or observation.
A single ask: a 15-minute call or a yes/no question.
An easy exit: a line saying they can tell you if it is not relevant.
Subject: [Specific topic] after PACK EXPO
Hi [First name],
[One line about the conversation, or the announcement you saw.]
We help [type of company] with [specific problem], and from what
[Company] showed this year, [one line on why it could be relevant].
I put together [useful resource] and can send it over.
Would a 15-minute call next week be useful, or is someone else on
your team better placed? If this is not a priority, tell me and
I will stop writing.
[Your name]
Fill every bracket with something specific. If you cannot, that company probably belongs in Tier C for now. It is better to send forty messages that each say something real than four hundred that could have been sent to anyone. Log every reply, bounce and opt-out in your CRM the same day, so the second and third touches only go to people who are still in the sequence.
Business-to-business outreach still has rules. If your contacts include people in the EU or UK, GDPR and ePrivacy rules apply, and similar laws exist in many other countries. In practice that means having a lawful basis for contacting someone, such as a documented legitimate interest or consent where required, telling people who you are and why you are writing, and honouring opt-out and unsubscribe requests promptly.
Keep only the data you need, such as name, role, company and business email, and remove records that bounce or ask to be deleted. If you buy or source contact data, choose providers that collect from public or opt-in sources and check addresses before delivery, and ask how the data was gathered. Rules differ by country, so check your approach with your legal team before you launch a campaign.
Sort exhibitors into tiers, read one signal per company, write to the right role and stick to a four-touch cadence. That order keeps the work manageable and your messages relevant long after the 2026 PACK EXPO floor has been packed away.
If you need contacts to start on Tiers B and C, you can request a custom contact list of PACK EXPO International 2026 exhibitors built around your industry, company size and job function, then begin with the segment closest to your ICP.
Follow up within one to two business days with people you met, and within the first week for everyone else. Early messages land while the show is still fresh and booth teams are back at their desks. After two weeks, your note competes with a full backlog and loses its context.
A good follow-up email has a short reference to the show or conversation, one sentence on why you are relevant, one useful resource, and a single clear ask such as a 15-minute call. Keep it brief, use a specific subject line, and give the reader an easy way to opt out.
Three to four touches over about a month is a sensible limit for most B2B outreach. Space them out, make each message add something new, and stop when the person replies or asks you to stop. Continuing after a clear no hurts your reputation and may breach opt-out rules.
Prioritize by context first, then by fit. Put people you spoke with at the top, then exhibitors showing a visible buying signal such as a product launch or expansion, then companies that only match your ideal customer profile. Each group gets its own channel, timing and tone.
It depends on the country and your lawful basis. In the EU and UK, B2B email falls under GDPR and ePrivacy rules, so you need a documented basis, clear identification and a working opt-out. Rules differ elsewhere, so check with your legal team. This is general information, not legal advice.
Write to the right role, not a general inbox, and lead with something specific to their business, such as a recent launch or announcement. Skip the long introduction, offer one useful point and ask a simple question. If you lack contacts, a sourced and checked contact list can fill the gaps.
